The 32-year-old, who scored 61 goals and registered seven assists in 51 appearances across all competitions during the 2025-26 season is currently being chased by Barcelona with one year left on his current contract.
Kane also took his overall World Cup tally to 11 goals, surpassing Gary Lineker's total of 10 thanks to a fine finish against Panama over the weekend.
The former Tottenham Hotspur striker’s future is up in the air as the World Cup continues and as reports link him with a move away from the Bundesliga.
Rooney, who has clearly seen the rumours, spoke on Kane this week and suggested he make a shock switch to the Red Devils to try and break the Premier League all time goalscorer record.
"I think everyone would have an interest. Listen, if Harry Kane’s not going to stay at Bayern Munich then I’d love him at Manchester United. If he’s listening: 'Harry, you’ve got Alan Shearer’s record there… help get Manchester United back!'."
"You think for Harry Kane, he’s won the Bundesliga and let’s say he goes to Barcelona, he wins La Liga… deep down he wants to win the Premier League. Imagine he comes to Manchester United and he’s the one to drive that, to get Manchester United back to winning the league."
Kane gone on to register 146 goals for Bayern, making him the seventh-highest goalscorer in their history after just three seasons.
He is by far one of the best strikers on the planet and if United are to make a move, they must do it quick as Barcelona seek to draw him away.
