The Red Devils are looking to bolster their goal-shy front line after opting not to sign up on loan AS Monaco striker Radamel Falcao and Robin van Persie's Old Trafford future looking anything but certain.
Spurs youth product Harry Kane was a revelation for the London club last season, ending the 2014/15 Premier League campaign as the top scoring Englishman with 21 goals, as well as being voted PFA Players' Young Player of the Year.
Sky report that Kane wasn't initially a target for Manchester United, but the clubs stance has now changed with United now looking to do a deal.
"It is a search for a striker that now includes Harry Kane and that is interesting," said Sky Sports reporter James Cooper.
"Things have changed in the last three or four weeks
He wasn't on Manchester United's radar then but I think he is now.
"He is on the list of possible deals that Manchester United might be tempted into doing this summer.
"What Manchester United are doing is looking at all their options
There certainly has been no bid at the moment between Old Trafford and White Hart Lane and no real negotiations at all.
"But what has shifted is that Manchester United have interest in the player
He is under consideration by Louis van Gaal."
However, just last month Harry Kane reaffirmed his desire to play for Spurs:
"Spurs are a big club and I have a bright future here," Kane said.
"I hope to continue scoring goals and doing well with the club."
