Jose Mourinho says Chelsea have concluded their activity in the January transfer window.
The Portuguese has moved to sign Mohamed Salah from Basle, with Juan Mata's move to Manchester United imminent.
Salah, who must pass a medical and agree personal terms, which is something of a formality, and become Chelsea's third signing of the month after Bertrand Traore and Nemanja Matic.
Traore is an 18-year-old prospect who was immediately loaned to Vitesse Arnhem, while Matic has been thrust straight into the first-team squad after initially departing for Benfica in the deal which saw David Luiz move to Stamford Bridge.
"Hopefully we are done," Mourinho said. "We are not bringing in a striker in this window."
Chelsea's initial intention this month was to solely go for Matic, a defensive midfielder, but circumstances and a fee from United too good to turn down will see Mata depart and Salah come in.
Mata and Kevin De Bruyne, who joined Wolfsburg, have departed for big fees and substantial profits.
Both play in a position in which Mourinho has numerous options.
It is a transitional period for Chelsea, yet they are still challenging at the top of the Barclays Premier League.
Mourinho, whose focus this weekend is on Sunday's FA Cup fourth-round tie with Stoke, said: "We would only have done Nemanja this window if we hadn't lost a player (Mata), but we are trying to keep the level and improve, to improve the team, to improve the squad, to change the style of play.
"And we're still trying to get results and still trying to win matches.
"We need that mixture of young players growing up and experienced players giving stability to the team.
"We are doing that. You can see what we're trying to do. Nemanja is 26, Salah 21, so we are trying to build a team for the future.
"We're doing fine. We're calm. In relation to the domestic competitions, Man City is Man City, an unbelievable level.
"Arsenal have had eight years building this team, and this team is perfect. They're also a strong contender."
Mourinho plans to field a strong team against Stoke as Chelsea bid to continue their fine recent record in the FA Cup.
The Blues have won the trophy in four of the last seven years, beginning when Mourinho won the cup in 2007 during his first spell.
With Fernando Torres out due to a knee injury, striker Demba Ba could be given a first start since October against a team which beat Chelsea in early December.
Chelsea have won six of their last seven, conceding twice, but Mourinho is wary of a repeat result against Mark Hughes' men.
The Portuguese said: "We lost against this team and it was not a long time ago.
"Everybody knows who Stoke is: very physical, very direct, very strong on set-pieces, they come here to compete.
"I expect a very difficult match. That's why I'm going to play with a strong team.
"I'm not going to make big changes in the team, because we are going to try to go as far as possible in the competition. We have to play with a very strong team."
Chelsea - January transfer targets
Chelsea - January transfer targets
1/18 Luke Shaw - Another potential long term successor to Ashley Cole, the Southampton youngster has impressed everyone and would surely command a fairly hefty fee given his side's recent success.
2/18 Sami Khedira - Currently out with a long term injury so a January signing looks unlikely but Jose Mourinho is said to be keen to link up with his former charge and the German is just the sort of player Chelsea need in midfield.
3/18 Fredy Guarin - At one point very close to signing with the club, the £15m Colombian, cooled for a while. However, with the move to Juventus, stalling - Chelsea may with the use the funds from Mata's transfer to Man Utd and make another bid.
4/18 Andrea Ranocchia - Chelsea are one of a few Premier League clubs chasing the Inter defender and you can see why, the tall centre-back is a handy player.
5/18 Claudio Marchisio - Juventus' early Champions League exit may leave them a little strapped for cash with Marchisio being mooted as a player to be sold in order to cover the shortfall. Chelsea would no doubt be interested in his midfield class should he become available.
6/18 Eliaquim Mangala - Another defender Mourinho is reportedly very keen on, the Porto centre-back would not come cheap although his club have admitted they would be willing to sell him for the right price. Manchester City have since shown an interest however.
7/18 Luis Suarez - Chelsea need a goal-scoring striker, so who better than the league's top scorer? A very unlikely move for a lot of obvious reasons.
8/18 Diego Costa - The Atletico Madrid man is another striker in red hot form and consequently he has attracted the attention of several Premier League clubs. Mourinho would no doubt enjoy swiping him from under Arsene Wenger's nose.
9/18 Xabi Alonso - Another of Mourinho's former players who would add experience and quality to Chelsea's midfield. Given his age shouldn't prove too expensive.
10/18 Radamel Falcao - Linked with Chelsea for some time, the free-scoring Colombian would cost a fortune to prize away from mega-wealthy Monaco, but the promise of Champions League football would surely be enticing.
11/18 Edinson Cavani - Another big name striker who would cost a lot to sign, this time from PSG, Cavani has again consistently been linked with a move to Stamford Bridge.
12/18 Hulk - Apparently fairly disenchanted at Zenit and another long time Chelsea target, nevertheless would seem an odd purchase given his usual berth is out wide - a position Chelsea have a ludicrous amount of depth in.
13/18 Jackson Martinez - Another Colombian reportedly on Chelsea's radar, the Porto forward has an excellent recent goal record but might represent more of a risk given he would still command a large transfer fee. With Juan Mata now in Chelsea's past, a new midfielder is needed.
14/18 Gonzalo Higuain - Seems unlikely given he only moved to Napoli in the summer, but Italian media are reporting that Chelsea are interested in the Argentine forward. Another of Mourinho's former men.
15/18 Wayne Rooney - Chelsea's main target over the summer and despite apparently being happier at Old Trafford has yet to sign a new contract. Failure to qualify for the Champions League would surely see Rooney depart. Will selling Mata to the champions make them loosen their tough stance on the England man?
16/18 Fabio Coentrao - With questions over Ashley Cole's place in the side, Chelsea are reportedly having a look at another Mourinho old boy, Real Madrid's Coentrao.
17/18 Mario Balotelli - Is a Premier League reunion with Super Mario back on the cards? That's what sections of the Italian press think. It seems unlikely given his previously very poor working relationship with Mourinho but you just never know.
18/18 Alberto Moreno - The young left back is another being touted as Ashley Cole's successor - with a buy out clause of £25m he wouldn't be cheap but then aged 21 he has a long future ahead of him.
