Bad news for Chelsea and good news for Newcastle, as Diego Costa may miss Saturday’s match.

A freak accident involving an academy player saw the Spanish striker receive a broken nose in training on Thursday.

Chelsea manager Guus Hiddink says that a lot will depend on whether Diego Costa feels comfortable wearing a mask in match conditions, after giving it a try in training on Friday.

After a poor start to the season, Costa has scored six goals in his last seven Premier League matches and would represent a slightly bigger threat than the useless Victor Anichebe did last week in the West Brom match.

Hiddink also today rued the freak injury that Kurt Zouma picked up against Manchester United last Sunday, landing awkwardly, the young defender has been ruled out for at the rest of this season and potentially longer.

The injury raising questions of whether potentially this could increase the chances of John Terry staying at Stamford Bridge after this season.

Guus Hiddink speaking at his pre-Newcastle press conference:

“In training yesterday (Thursday) Diego Costa got in a duel, got his nose broken. It was not Oscar. It was one of the youngsters from the academy.

“He put his nose on the back of the head and was very unlucky. His nose was broken

“He will return today because today is the day they put on a mask. We are a team with a lot of masks.

 “I think he will be available. I hope. I’m not sure, but I think he might be available.

“It is real shame Zouma will be out for so long, especially as he was in good form and the Euros in France are coming up.

“That (whether John Terry might now stay at Chelsea after this season) is something to be answered by the board and the directors of the club.”
