Manchester United are currently short in attack as Ole Gunnar Solskjaer decided to let go of Romelu Lukaku during the summer.
United have struggled to get the goals this season with just five goals in the last six Premier League games.
Lukaku scored 42 goals in 96 appearances for United having moved to Old Trafford from Everton in the summer of 2017 for a fee of £75m.
Reports claim Manchester United are planning to buy a new striker in January, but Solskjaer has revealed that he has no regrets letting go of the Belgian.
“I can say [I am a striker short], but that was the decision that I made and I made it happily,” the Manchester United boss told Sky Sports.
“When you have players, [they may have] great potential, but Romelu’s head was not here for us working forward as a group.
“I don’t want to speak too much about other players. I have got lots of respects for Romelu but his time was up here.
“We are very happy with the recruitment we did. Towards the end the right one we just didn’t get him over the line.
“You’d rather bite the bullet and wait because you don’t want to spend big amounts of money on something that you are not sure of.”
