The 30-year-old arrived at Old Trafford on loan from Burnley this month and scored his first goal for the club in a 3-0 win over Nottingham Forest on Wednesday night in the first leg of the Carabao Cup semi-finals.
The Dutchman was brought in on loan after Cristiano Ronaldo’s exit and amid Anthony Martial’s ongoing fitness struggles, but he has quickly been trusted by manager Erik ten Hag.
Weghorst has already started two Premier League matches and the EFL Cup victory over Forest, with the giant striker impressing Keane in the process.
After watching the Netherlands international score on Wednesday night, Keane told Sky Sports: ‘Great finish, look at his reactions.
‘People have been critical that he’s come to the club. That’s what he’s been brought to the club for. Huge goal for United.’
Keane admitted that he doesn’t exactly expect Weghorst to break records at Old Trafford, but thinks he is a good option to fill in before United sign a more permanent option up front in the summer.
‘Man United had to bring someone in. The manager made it clear, there was no money to spend. They lost Ronaldo, questions marks about Anthony Martial’s fitness… so I can see why they gambled on him,’ said the former Manchester United captain.
‘I don’t think he’ll be a prolific goal-scorer but if he pops up with the odd important goal like that and he helps Marcus. He’s an international player – he’s no mug!
‘The perception about him, because he struggled in a Burnley team that were having a difficult season, people kind of judge him on that. Give the guy a chance, he scored an important goal for United tonight. Good luck to him.
‘His lack of pace can be a problem when United are trying to play on the counter-attack but they’ll need to play to his strengths. He linked up well, took his goal well. There’s a reason he came on loan, because he’s obviously not top level. But the important thing is that the manager knows him well. You need characters in your dressing room.’
