Manchester United legend Roy Keane says Romelu Lukaku must do better.
Lukaku drew a blank in last night's Champions League stalemate at Sevilla.
And Keane declared: "Man United's problems are not just with Pogba. Lukaku's got to do better. Sanchez – I know he's new to the club – he's got to do better.
"They obviously need to reinvest in some defenders.
"You can't keep pointing the finger at Pogba but of course the lad has got to do better."
Lukaku, who had a goal disallowed for handball in Seville, has scored 21 times in his first season as a United player, but Keane is frustrated by the Belgian's general play.
"You're talking about Man United, one of the greatest clubs on the planet," said Keane. "They still need to do better. And certain players need to up their game.
"Lukaku, for example — get hold of the ball. Whatever about putting the ball in the back of the net, get hold of it.
"And if you want to became one of the great strikers of Man United and you get the chance, like he did tonight, you've got to score in these tight games."
