Newcastle United boss Steve McClaren has challenged Moussa Sissoko to step up his game.
The 26-year-old France international has veered between brilliant and ineffectual during his time on Tyneside.
"He's obviously very ambitious and that's great, but like everybody who is ambitious, I'm sorry, but you have to perform every week to a certain standard, and he knows that," said McClaren.
"I'm sure he admits himself he could do better, but his work for the team, his stats and his running, all that high intensity, is more than he was doing last season, so he's certainly doing his job and putting the effort in."
