Manchester United has been reminded yet again of their £50 million transfer blunder.
During the summer of 2019, when Manchester United bought Aaron Wan-Bissaka, they were quick to point out that they had sifted through a database of 804 right-backs before selecting the Crystal Palace player of the year as their first option.

It told us that United's computers had a lot of memory, but it didn't tell us anything else about recruitment, which was surprising given that Wan-Bissaka was the player they had been associated with during the transfer window and always appeared to be the most logical choice.

Since Wan-Bissaka no longer plays for Manchester United, it would be interesting to know who the other 803 right backs on that list were. It seems like most of them have been chosen by England since. Wan-position Bissaka's on Gareth Southgate's list of possible right-backs is around eight hundred and forty-fourth on the scale.

Apparently, Wan-Bissaka was the perfect fit for the "culture reset" that Ole Gunnar Solskjaer and Ed Woodward had determined United required in the summer of 2019.

The Norwegian coach believes that the player "has the appropriate work ethic, talent, and temperament" to play for Manchester United, and that he "fits exactly the type of player that we are trying to bring into the group to help us progress and push on further."

Wan-Bissaka had settled in well by September of this year, and he was called up to the England squad for the first time. With his departure due to a back issue, it is looking more and more like his Three Lions career will come to an end in the first and final act.

After selecting four right-backs for his provisional European Championship squad - Trent Alexander-Arnold, Reece James, Kyle Walker and Kieran Trippier - in the summer of 2016, nobody was surprised when Wan-Bissaka was not even mentioned in the discussion.

Two other English right-backs who pleased Southgate a year ago were named by him as well. Among the players he was keeping an eye on were Aston Villa's Matty Cash and Leeds United's Luke Ayling, while he also had kind words for the Under-21 team's Max Aarons.

At right-back, the summer's embarrassment of riches has turned into a drought as a result of a lack of consistency. Walker was informed that he would not be playing in the international friendlies against Switzerland and Ivory Coast, therefore James and Alexander-Arnold joined Trippier on the sidelines of the match.

The possibility that Southgate would turn to a Manchester United right-back valued at £50 million was never seriously considered by anyone. Instead, he called in Crystal Palace's Tyrick Mitchell, who initially replaced Wan-Bissaka and has spent much of this season playing at left-back, and Southampton's Kyle Walker-Peters to the squad.

In total, Southgate has called up or cited nine English right-backs ahead of Wan-Bissaka, and while the England manager's decision is far from final, there hasn't been a line of experts waiting to tell him he's wrong.

Even though Wan-Bissaka has made 124 appearances for the Red Devils thus far in his career, he has only started six of the team's last 20 games since the appointment of Ralf Rangnick.

His offensive game has not improved over the last three seasons, and it's becoming increasingly difficult to avoid the conclusion that he just does not provide United enough in the final third from a position that has become critical in modern football, particularly for elite clubs.

Rangnick prefers Diogo Dalot because to his increased attacking desire, but the Portuguese full-back was on the verge of leaving the club in the summer and still has work to do if he is to be considered a long-term option.

Wan-arrival Bissaka's at Manchester United cost the club £50 million, yet it already appears like the midfielder has limited future at the club. It's difficult to imagine him succeeding in a more offensive, innovative club this summer under the guidance of coaches such as Erik ten Hag or Mauricio Pochettino.

With the exception of Walker and Alexander-Arnold, Wan-Bissaka is a far cry from the right-backs at the clubs with which United plan to compete in the Premier League this season. In one-on-one scenarios he may be great defensively, but he isn't always switched off protecting the back post when opponents attack down the left, and his offensive production is nowhere like that of the other three.

Even England is prioritizing making a contribution going forward, and as a result, Wan-Bissaka is nowhere near being considered for international selection. That appears to be a significant indicator of his future at Old Trafford.
