Manchester United have asked West Ham to raise their offer for right-back Wan-Bissaka, according to United Kingdom's Daily Mail, while the Hammers are said to be preparing a new bid. Their initial price of £10 million was rejected by Manchester United.

Under new manager Julen Lopetegui, West Ham have been active in the transfer market, bringing in a number of new signings. However, they have yet to sign a right-back. The team had hoped to bring in the 26-year-old Mazraoui from Bayern Munich, but could not reach an agreement due to the agent's commission issue and decided to bring in Wan-Bissaka instead.

According to the Daily Mail, after rejecting West Ham's initial offer, Manchester United have made it clear that they want to sell Aaron Wan-Bissaka for £18 million. The 26-year-old has only one year left on his contract and United are ready to sell. The two clubs remain at odds over the player's valuation, and they are trying to reach an agreement before the start of the new Premier League season.

The Daily Mirror reports that Aaron Wan-Bissaka is still involved in Manchester United's pre-season tour in the United States despite being on the transfer list, largely due to the lack of fit and available players. As a result, United boss Erik ten Hag is keen to sell him in order to bring in his own former Ajax player, Mazraoui.

Aaron Wan-Bissaka was unexpectedly injured in the Manchester United clash with Liverpool and his injury is currently undetermined, and if it is too severe, it could affect a potential transfer deal. Inter Milan are also interested in him, but the Serie A champions could also wait for his contract to expire next year before bringing him in for free.

In Manchester United's warm-up matches, Aaron Wan-Bissaka's assist ability was once again criticized. In one attack, Rashford advanced down the left and, after linking up with Sancho, the ball was transferred to the feet of Amad · Diallo on the right, who broke through and passed the ball back to Wan-Bissaka. However, "Spider-Man" gave up the ball to his opponent with a random cross.

Aaron Wan-Bissaka has a world-class level in one-on-one defence and tackles and can be used to defend breakaway wingers. However, his assists, positional sense and defensive awareness have not improved over the years, and when he encounters a winger who is not dribbling but running, he often misses and has a weak header, which can become a shortcoming in the defence.

In contrast, Mazraoui is not very strong defensively, but his handling of the ball and his level of assists make him a good fit for Ten Hag's tactical play. Morocco can score with left and right, and even with a left-footed shot!

In his final season at Ajax, the year before Ten Hag's departure, Mazraoui scored five goals. Rumours suggest Manchester United have scheduled a medical for Mazraoui on Tuesday, but Aaron Wan-Bissaka's departure could lead to a chain reaction.

Bayern are also likely to raise their asking price and hope to get around £25.5 million before selling Mazraoui. If he joins Manchester United, Mazraoui will strengthen United's wing-backs and move to the right-back positionDiogu · Darlow brought competition and even took his place.

A number of first-team players that United want to sell this summer have failed to leave due to price, including Casemiro, Jadon Sancho, Victor Lindelof, Scott McTominay and Hannibal · Mejbri. This has affected the team's transfer budget, and United will need to sell more efficiently in the trade market if they want to accelerate the rebuilding of their squad.
