Boro v Chelsea Chelsea make the trip to the Riverside this Saturday and will be wary of the fact they’ve lost there in the league twice in the last three seasons.

Manchester City winger Martin Petrov is facing a lengthy lay-off after suffering knee ligament damage, City boss Mark Hughes has confirmed.

The Bulgarian international was injured in his country’s midweek draw with Georgia.

“Martin is going to see a couple more specialists over the weekend. But the view is, he has a significant injury and could be out for quite some time,” Hughes said.

“He has ligament damage and the initial scans do not look good. Martin had 10 minutes in one game and 20 minutes in another before going to play for his country.

“It is a big ask for players and they are at risk on occasions if they have not had the required time on the pitch beforehand.”

Hughes was expecting Brazilian forward Robinho back in Manchester on Friday after he was substituted with a thigh injury during a draw with Colombia in midweek.

“We have heard nothing from their medical department, so we are assuming he is fit and well,” said Hughes.

“We have seen the incident where he had the injury and had to come off. It does not look like a significant injury, just a clash.”
