Manchester United interim manager Ralf Rangnick has said that the Red Devils will only enter the January transfer market if they can sign a player "that improves the whole team".
The 20-time English champions continue to be linked with a number of players ahead of the winter window, with RB Leipzig's Amadou Haidara thought to be a leading target.
Rangnick has suggested that the club could be active at the start of 2022 if a "high-quality" individual with "a built-in winning mentality" becomes available.
"My opinion on winter transfers is clear. It needs to be a player that improves the whole team. It needs to be a high-quality player, no matter what area of the pitch," Rangnick told reporters.
"If it's a midfielder or whatever it is, it needs to be a player that really helps us to get better. On the other hand it needs to be a player that can perhaps move in the winter, then discussions can begin to be made. But only then if those two things come together will it serve us well.
"We also need, for this competitive league, to have the best possible mentality. They need to be mature and have a built-in winning mentality. For me, mentality is even more crucial than anything league in the world.''
Rangnick has also revealed that he is open to players leaving Old Trafford on loan in January, while Anthony Martial's agent has said that the Frenchman wants to depart at the start of 2022.
