The Spaniard has been Chelsea's best player till now with the Blues' campaign hitting a few roadblocks on the way. Antonio Conte’s side is sitting on the seventh place after a disappointing 3-0 loss to rivals Arsenal.
Costa was the subject of interest for Atletico Madrid in the summer but Chelsea were in no mood to let go of their prized asset. That was one of their smart decisions in recent times as Costa has proved his worth with six goals this season making him the top scorer in the Premier League at the moment.
The 27-year-old scored the winner in Chelsea's first two games against Watford and West Ham while scoring a stunning overhead kick against Swansea to salvage a draw for Chelsea. He has also scored against Hull and Liverpool this season while also producing two assists along the way.
Antonio Conte is getting a taste of English football early in his first season but he has an able striker at his disposal who has shown time and again that he is a world class player with deadly finishing skills that can give Chelsea the momentum to push for a top four spot.
