The Spanish striker, who scored 26 goals in 46 games for the Premier League champions last season, had been strongly linked with a return to Atletico Madrid this summer before their transfer ban while a big money move to China has long been mooted.
And Costa claims Conte has messaged him already this offseason to tell him he is no longer needed at Stamford Bridge.
"I'm a Chelsea player, but they do not want me there," he said after Spain's 2-2 draw with Colombia on Wednesday night. "Antonio Conte has told me by message that I do not follow at Chelsea and that's it. Conte said he did not count on me for next season.
"It's a shame, I've already forwarded the message to Chelsea people to decide. But it is clear that the coach does not count on me and does not want me there. You have to find a team."
The striker has his heart set on a return to Atletico Madrid, though that move would be delayed due to the Spanish club's transfer embargo.
"It would be nice to return to Atletico, but it is difficult to be four-five months without playing," Costa added in quotes reported by Marca. "Being five months without playing? I do not know, it's complicated, but people know that I love Atletico a lot and that I love living in Madrid.
Chelsea summer transfer targets
Chelsea summer transfer targets
1/10 1. Alvaro Morata, Juventus
Chelsea are reported to have already agreed a deal with the Spaniard, who has scored 15 league goals compared to the 9 of Karim Benzema despite playing 3 less games, but is often sidelined by the Frenchman, contributing to Morata’s openness to a move this summer. €70m is the rumoured fee for the 24 year-old, which could happen if Chelsea fetch the £75-80 million it is thought Tianjin Quanjian will pay for Diego Costa.
2/10 2. Franck Kessie, Atalanta
The first of many Serie A players on the list is Atalanta’s Franck Kessie, who scored six goals in 32 in the league from central midfield. The 20-year-old is subject of an offer from Roma, but it is thought that Conte sees the energetic Ivorian as a good option for the coming season and could intervene if the player decides to leave. A sum of just over £20m is expected to be enough to secure Kessie’s signature.
3/10 3. Antonio Rudiger, AS Roma
The German centre back is one of two Roma players in contention this summer. At 24, Rudiger has been capped 12 times by the World Champions and has been a standout figure at the back for his club. He is quick for a centre half, comfortable on the ball and is relatively versatile having played all across Roma’s back line during his time at the club. His price has been touted as £70m combined with the second Roma player on this list.
4/10 4. Radja Nainggolan, AS Roma
Fiery midfielder Nainggolan was the target of a Chelsea bid last summer, and it is thought that Conte could prise him away from Italy this time around, as part of a double swoop with Antonio Rudiger at £70m. He is a player the former Juventus manager knows very well, and would fit perfectly into Chelsea’s side with his combative style. While Roma will be desperate to avoid letting two key players go in one hit, it may be difficult to turn down the right offer.
5/10 5. Alex Sandro, Juventus
Sandro is emerging as one of Europe’s finest left backs and the Juventus man will be high on Conte’s list of targets. He is far more mobile than Marcos Alonso and would unlikely find it difficult adapting to Conte’s methods, which are largely similar to that of current Juventus boss Massimiliano Allegri. The player is also being tracked by Manchester City, and could cost upwards of £40m.
6/10 6. David Stockdale, Brighton
Asmir Begovic is likely to leave Stamford Bridge in search of regular first-team football, and David Stockdale is an option for Chelsea. The 31 year-old keeper is out of contract this summer and helped his current club secure promotion to the Premier League this season. However, his error in the final game gifted Aston Villa an equaliser and Newcastle top spot in the Championship, and Stockdale later posted on twitter that he was ‘gutted to go out like that’ and thanked Brighton’s fans and staff, adding fuel to the fire over the exit rumours.
7/10 7. Ben Gibson, Middlesbrough
Gibson’s stellar performances have been widely recognised over the course of this season and the 24-year-old centre back has worked his way into the England set-up. He is in a similar mould to the departing Terry and Conte is supposedly a big admirer of the £30m rated Middlesbrough man.
8/10 8. Romelu Lukaku, Everton
Ex-Chelsea frontman Lukaku is expected to finally leave Everton this summer, and was recently spotted with the West London club’s technical director Michael Emenalo after Everton’s loss at Stamford Bridge in April. Despite this, Manchester United are thought to be in the driving seat for his signature amid concerns from the player over whether he would fit into Conte’s strict system. A £74m transfer is possible, but could be scuppered by Mourinho’s interest.
9/10 9. Andrea Belotti, Torino
Another forward linked to Chelsea is Andrea Belotti, who at 23 has his best years ahead of him. The €100m release clause, applicable only to clubs outside of Italy, which was negotiated into his contract by club president Urbano Cairo, makes a move seem increasingly unlikely; nonetheless, the Italian is at the very least on Chelsea’s radar this summer.
10/10 10. Alexis Sanchez, Arsenal
Arsenal forward Alexis Sanchez is thought to be seeking a move away from the Emirates this season after the Gunners’ disappointing campaign. He has stalled over signing a new contract, and with his current deal expiring next summer, Chelsea’s London rivals are at serious risk of losing their star man. While Wenger has insisted Arsenal no longer have to sell their best players, it could become a difficult situation if Sanchez wishes to stay in the capital and tries to force a move to Chelsea. Considering his contract situation, £55m could be enough to acquire the Chilean, with Bayern Munich apparently ready to offer exactly that at the start of the window.
"It would be nice to go back, but it's difficult to be four-five months without playing. It's a World Cup year and there's a lot to think about. I need to play, that's all. "
Costa did not feature for his Spain in the friendly in Murcia,where Manchester United target Alvaro Morata scored a late equaliser.
He joined the Blues in 2014 for a £32million fee and has bagged 58 goals in 120 games, winning two Premier League titles and one League Cup.Reuse content
