Manchester United are reportedly keen to bring four new players to the club during this summer's transfer window.
The Red Devils, who finished second in the 2020-21 Premier League before losing the Europa League final, are said to be currently in talks with Borussia Dortmund over a deal for Jadon Sancho.
According to the Daily Star, the 20-time English champions are keen to secure a move for Sancho as soon as possible, while three other signings are also being lined up.
The report claims that Atletico Madrid's Kieran Trippier has been identified as the ideal player to provide competition for Aaron Wan-Bissaka at right-back, while Aston Villa goalkeeper Tom Heaton is expected to return to Old Trafford on a free transfer.
Man United are also allegedly determined to sign Real Madrid's Raphael Varane, as head coach Ole Gunnar Solskjaer looks to bring in a long-term centre-back partner for Harry Maguire.
The Red Devils have also been linked with Tottenham Hotspur's Harry Kane and Borussia Dortmund's Erling Braut Haaland, but are seemingly unlikely to spend big on either player this summer.
