United's recent failure to convert chances was a major factor in their Premier League draw at Burnley and FA Cup defeat by Middlesbrough.

Cristiano Ronaldo's future is also uncertain, while Edinson Cavani is out of contract this summer and Mason Greenwood currently unavailable.

United are long-time admirers of Norway frontman Erling Braut Haaland.

"This is obvious," said Rangnick of the situation. "Edinson's contract is running out in the summer and the club needs the best possible centre-forward. I think everyone is aware of that."

Prolific Borussia Dortmund striker Haaland knows Rangnick as the German helped broker the deal that saw the 21-year-old move to Red Bull Salzburg in 2019.
