The Senegal international has started all of the Magpies' five league matches so far this season but is yet to find the back of the net, despite hitting a sensational 13 goals in 14 appearances following his arrival in January from Freiburg.

The Magpies manager later commented that he regretted his team’s choice of penalty taker, but insisted he was unconcerned about the striker’s form.
Pardew told reporters: "He is one of those players who doesn't really carry too much baggage, if I am honest.
"I don't see an overriding problem there. I just know with Papiss that one goal, one moment will get him back into the groove. He's a great player, and like all great players you have got to stand by them."
He went on to recall France international Hatem Ben Arfa’s struggles with form and injury following his arrival on Tyneside, drawing on his excellent assist for Ba’s goal as evidence of the reward his club received for persisting with the talented attacker.
"We stood by Hatem when he was not at his best and look at him now. In a kind of forgettable game, I am guessing for most people, especially neutrals, there were four or five moments from Hatem that you could put in a World Cup," Pardew continued.
"They were really special and that's where he is at the minute, he really is playing well."
