Chelsea midfielder Cesc Fabregas was happy for Diego Costa after his goalscoring return against Hull City.
Cesc says it's clear how important Costa is to the team.
"It was a good goal and he's always there when we need him," said Fabregas.
"We know what Diego brings to the team, nothing needs to be said about that. We're pleased he's back and we need him if we want to achieve our targets."
