John Terry has risked angering Jose Mourinho after claiming he is not sure where claims that Diego Costa in injured have come from.
Mourinho has claimed that the Chelsea striker is at risk of aggravating a troublesome hamstring by reporting for international duty with Spain next week. The Chelsea manager has also claimed that the 26-year-old has barely been able to train in between matches.
However, according to Chelsea's captain, Terry, Costa is fighting fit and causing him quite a problem in training.
He told The Telegraph: “I’m not sure where that’s coming from. He certainly isn’t showing that against me in training.
"He is training every day, he looks sharp, he looks angry, he looks aggressive. He’s fit at the moment and that’s the main thing.”
Diego Costa himself claimed his game was being hampered by injury, leaving Chelsea's rivals fearing just how good he is when full fit.
He said in a recent interview with El Comercio: "I don't want to be in the middle (of Spain and Chelsea). Mourinho has not told me anything.
"I'm here ready to play. I've had some problems but it's getting better. I've already played three games in a week and the coach (Vicente Del Bosque) knows that I carry some problems but I will treat them during the week."
Costa's form on the pitch certainly suggests that he is playing his best football. So far, Costa has scored an incredible nine goals in just seven Premier League starts, helping Chelsea to a five-point lead at the top of the table.
As a result, Vicente Del Bosque decided to included the Brazilian-born striker in his Spain squad to face Luxembourg and Slovakia over the international break, much to Mourinho's dismay.
Premier League competition
Thanks to the likes of Costa, pundits are beginning to forecast a runaway title win for Chelsea. Already five points clear of Manchester City, the Blues look too strong for their Premier League rivals.
However, Terry insists that the strength of Chelsea's rivals means the title race is far from over.
“The quality in the league is getting better,” Terry said. “Clearly it’s not over – other teams have been in that position. It’s nice to have the lead, but when you’re at the top everyone wants to shoot you down from top to bottom.”
While Costa can enjoy a handful of years at Stamford Bridge, for Terry this could well be his last. He is currently in his 15th year with the club after agreeing a one-year extension worth £175,000-a-week. However, with the likes of Kurt Zouma pushing for a first team spot, he may be shoved out the door in similar fashion to Frank Lampard.
