Robbie Savage has revealed that Diego Costa’s temperament is his one concern about the striker.
Costa signed for Chelsea from Atletico Madrid this summer and although Savage thinks his purchase makes the Blues a stronger team he is worried that he could be wound up too easily.
The Brazilian born centre-forward has been known for his fiery attitude on the pitch and has regularly squared up to other players during his career so far, meaning Savage fears that the physicality of the Premier League could test his restraint.
He wrote for the BBC: “If they had had a better centre-forward [last season] then I think they would have won the league quite comfortably."
“If you look at the players [Jose] Mourinho has brought in over the summer, then I think he has solved that problem."
“Costa was prolific for Atletico Madrid as they won La Liga and reached the Champions League final but he is not just a goalscorer - he can lead the line on his own, create chances and also bully opposing defenders."
“In terms of his physical stature and aggression, Costa suits the Premier League down to the ground and can play the same role for Chelsea that Didier Drogba did during Mourinho's first spell at Chelsea."
He added: “My only worry about him is that he might get distracted by his personal battle with defenders who try to wind him up."
“I have watched him a lot in La Liga and saw him react a few times this season. You can bet that players will be trying the same thing now he is in England.”
Despite his questionable discipline, Costa is expected to be a fantastic signing at Stamford Bridge.
He has already impressed during pre-season so far, scoring a clutch of goals and wowing fans with his presence and finishing prowess.
The 25-year-old forward scored 27 times last season for Atletico Madrid, as they claimed the title as champions of La Liga, and a similar feat in England would surely see him collect his second winners medal in as many seasons.
Chelsea were short of a clinical centre-forward, but Costa’s arrival is expected to solve that problem and he is one of the reasons that Mourinho’s side have gone in as the bookies’ favourites.
Another is the arrival of Cesc Fabregas and Filipe Luis, who have added depth to Chelsea’s squad in two areas where they needed strengthening.
And Savage feels that this trio, who set the club back around £80 million this summer, have made the London outfit the stand-out side in England’s top flight.
“They look so powerful and dynamic,” he said. “This is Mourinho's team now, and I would say they are the clear stand-out team in the Premier League.”
