There is absolutely no doubting of Diego Costa's ability. The 26-year-old scored 20 goals in the Premier League last season and has pace, power and the ability to beat a man.
However, the Chelsea striker has been a controversial character of late, the victim of many fingers blaming him for the sending off of Arsenal's Gabriel on Saturday, provoking the Brazilian several times after grappling with Laurent Koscielny.
The Stamford Bridge star has been involved in many incidents in his career; charged by the FA last season for a stamp on Liverpool's Emre Can, and the centre of attention on several occurrences when playing for previous club Atletico Madrid.

Costa is a professional footballer and is a role model for many young players and fans. There is no need to react with such violence on the pitch, or provoke opponents, especially when the Spain international has so much ability, and the potential to lead a fabulous career.
If Costa continues to act in such a manner, he will be a target for other teams, that will set out to try and provoke him, and prevent him playing his natural game.
Many believe the Brazilian-born forward is in the same mould as the Chelsea manager, Jose Mourinho, an extremely competitive man that is known to exhibit a naughty side.
Chelsea find out today if Costa will face a ban for his behaviour on Saturday, and the Blues could do without their star striker on the sidelines.
Backup options include Columbian Radamel Falcao, who had a poor season at Manchester United last season, in addition to Loic Remy, who is yet to prove himself at a top Premier League club.
Costa needs to improve his behaviour, and let his feet do the talking. Mental strength is a huge aspect for any Premier League football, and can be the difference in where Chelsea finish this season.
Is Costa becoming a hindrance for Chelsea? Have your say below!
