2. Diego Costa:
Costa is struggling along with his team. The Chelsea frontman has scored only 1 goal and assisted 1 in his 6 starts for Chelsea. Both of those came in Chelsea’s match vs West Brom, where they managed to somehow get 3 points (Chelsea won the match 3-2). Costa was involved in Gabriel Paulista’s(Arsenal) controversial sent off in the match between Chelsea and Arsenal. It was he who started the fight and he managed to buy a red card for Paulista. Chelsea won the match 2-0, however, Costa should turn his anger into goals if Chelsea needs to get back on track in the Premier League.
