Manchester United manager Erik ten Hag confirmed the reasons for his side signing a new left back.
The Red Devils have brought in a Tottenham defender on loan in Sergio Reguilon.
The Spaniard, who United chased three years ago, is coming in to cover for Luke Shaw and Tyrell Malacia, who are both injured.
"He is here, he trained," Ten Hag told reporters.
"He is a very experienced player, a player for big clubs, a player that's played already a lot of games in La Liga, in the Premier League," he explained.
"So, he has a very good background, we have seen he can play very intense football, so we are happy.
"While we had a problem with Luke Shaw injured, Ty[rell] Malacia injured, they are, for [the] long term, out, so I think we responded very well in that emergency situation."
