Wolves midfielder Michael Kightly has flown to Barcelona for treatment on his knees, reports the Birmingham Mail. It is believed leading specialist Ramon Cugat - who has treated Cesc Fabregas, Fernando Torres, Mikel Arteta and top tennis pros including Rafael Nadal - was his destination.

"He's been to see a specialist in Barcelona a few times for a quite aggressive treatment, so he's doing his best to get through it and then get back," revealed boss Mick McCarthy.

"He gets an irritation to the patella tendon in his knees so he's having ongoing treatment and he'll be out for as long as it takes.

''For me to elaborate any more I probably wouldn't do it justice, but he has to get shut of that discomfort.

"We're not going to rush him back.

"It's hard for him because he got back and played three games before twisting his foot against Birmingham. So we've said to him 'take as long as it takes - get yourself back'. Will he be back this season? I'm always optimistic - he might score the winner that keeps us up."
