Having watched Diego Costa closely for three years at Stamford Bridge Chelsea fans know what it's like to have that player that everyone else hates, even if it is a love-to-hate relationship.
Costa was the league's ultimate villain and he played the role perfectly with growls and pushes, fights and goals. He was the perfect Jose Mourinho striker and became a lethal weapon under Antonio Conte, too.
It's a type of striker that the Italian manager likes. At Inter Milan he got the nasty side out of Romelu Lukaku and transformed him into a world-class forward; now at Tottenham he has another player designed to rile up opponents and catch them unaware moments later.
