Manchester United’s interim boss, Ralf Rangnick, has given at least three conditions a player must meet before he approves a move in the January window.
The German will take charge of only his second Premier League clash on Saturday against Norwich.
Rangnick saw his side beat Crystal Palace 1-0 and draw 1-1 with Young Boys in the Champions League.
The 63-year-old, who has signed a two-year consultancy deal at Old Trafford, already has one eye on the future and how arrivals could help to bring silverware back to United.
“My opinion on winter transfers is clear. It needs to be a player who improves the quality, who helps the team to get better. It needs to be a high-quality player, no matter which area of the pitch.
“On the other hand, it needs to be a player who, if they were available in the summer, they’re available for similar conditions in the winter. Then it might make sense.
“It needs to be the right mentality as well as the right quality. For this competitive league, we need the best possible mentality. He needs to be mature enough, have a winning mentality, and for me, the mentality in this league is even more crucial than in any other league in Europe,” Rangnick said.
