The Mali international has weighed in with an important five goals in 16 appearances when coming on as a sub this season and he believes he has a future at the club under Roy Hodgson.
Sako’s deal expires in six months and it’s unclear if Hodgson is prepared to offer the 29-year-old fresh terms, even though he’s now fully fit following a succession of previous injuries.
When asked if he wants to stay beyond the end of the season, Sako said: “Yes, of course. I am just enjoying my football at the moment, so I am not really focused on my contract situation.
“It’s not about my personal situation, I just want to help the team and we’ll see at the end of the season. Fingers crossed I am injury-free now and I am enjoying my football.
“I have had to recover properly after training and matches, to do things right. I was doing that before but I was just unlucky. I don’t know why I was getting injured but now I am really happy.”
He added: “I have been injured a lot, so the manager has been playing me up front, so right now I am really enjoying it and it’s good for me.”
