Chelsea forward Diego Costa arrived in the Premier League with a daunting reputation, but has been under scrutiny after his conduct in the Capital One Cup Semi-Final 2015. The Blue’s striker was attempting to grab the ball for a throw-in when he came down hard on the lower part of Liverpool's Emre Can's right leg. The 21-year-old German was left writhing on the turf in pain but referee Michael Oliver allowed play to go on as normal after the incident, with Costa avoiding a card. Good guy or bad guy? We leave that to you, but we do know you can’t avoid owning the Chelsea F.C. Mask Diego Costa. Should we start packing your order?
