Inter, at one stage of the season top of the table, have faltered in recent months, taking only 13 points from 11 games since mid-November, dropping to fifth place, seven points behind the leaders Juventus.
In their last three matches, Inter have been beaten 2-0 by Bologna and have had draws against Udinese and Perugia, prompting protests by fans about the club's English coach, Roy Hodgson.
The club owner, Massimo Moratti, said: "We've got the players, it's the way that they play that has to improve and to do that we're going to have to train harder and show more determination."
Lazio come into the game just three weeks after replacing their Czech coach Zdenek Zeman with Italy's 1982 World Cup winning captain, Dino Zoff.
Zeman's sacking came at the end of a disappointing run which has seen Lazio slump to 11th place, 11 points behind Juventus, and also go out of both the Uefa and the Italian Cups.
Franz Beckenbauer, the Bayern Munich chairman, has told his players that they will have to stop acting like prima donnas if they want to win a record 14th German championship.
The former World Cup- winning coach and captain was very critical of the team in the first half of the season despite the fact they went into the two-month winter break in December at the top of the table. They held on to that position yesterday as the season resumed, with Jurgen Klinsmann scoring twice for Bayern in a 3-0 home victory over St Pauli. The former Tottenham striker, often criticised in the first half of the season for his lack of sharpness in front of goal, scored in the 28th and 75th minutes.
The Brazilian Sonny Anderson struck twice as leaders Monaco beat Le Havre 3-0 in the French League to move seven points clear of second-placed Paris St Germain.
PSG had cut the gap between themselves and the leaders to four points after their first victory for nearly three months with a 2-1 win at Lens on Thursday. The game was interrupted for 10 minutes after a linesman was knocked out by a missile thrown from a section of the stands.
The incident will be the subject of an inquiry and could lead to Lens being banned from playing one or several matches in their stadium.Reuse content
