Manchester United might sign the 2022 World Cup left-back for £25 million! The transfer is being postponed, with Carrick set to evaluate two young talents first.

The primary objective for Manchester United this summer is to upgrade the midfield. At present, only Ederson has been signed for £39 million, and the Brazilian has not been formally unveiled. But Jason Wilcox's transfer team is not hurrying, because the summer market hasn't officially begun. United have a strategy: after reinforcing the midfield, they will turn their attention to strengthening the left-back spot, and other positions will be addressed based on who leaves the squad.

According to the Manchester Evening News, United are now more likely to sign a new left-back than a left winger. Carrick reportedly views Danish international Patrick Dorgu as a winger, meaning the team already has two left-sided attackers in Cunha and Dorgu, while Rashford hasn't been sold yet. So bringing in another left winger is currently impossible.

In contrast, United have no left-back available. Tyrell Malacia has already been announced as leaving when his contract expires at the end of the month. That leaves Luke Shaw as the only natural left-back in the first team. Although both Diogo Dalot and Mazraoui on the right can fill in, it's unrealistic to rely on such an arrangement for a Champions League season.

United have been linked with several left-backs, including Newcastle's Lewis Hall, Arsenal's Myles Lewis-Skelly, and Barcelona's Alejandro Balde, all on the potential list.

However, some previous candidates are now completely off the table. Eintracht Frankfurt left-back Nathaniel Brown is close to a €55 million move to Bayern Munich, preferring to join the Bundesliga champions. Meanwhile, Chelsea's Marc Cucurella wants to return to La Liga, and staying at Chelsea is more likely than joining United.

But another left-back has emerged as the new focus of United rumors: Fulham's US international Antonee Robinson. Sky Sports in the UK also believes he could join United to compete with or even replace Luke Shaw. The 28-year-old started in the World Cup opener and could be available for just £25 million, making him a cost-effective option. In contrast, Newcastle's price tag for Hall is at least double that.

For now, United will not push forward with a left-back signing. They will wait until the midfield reinforcement is completed, possibly even until the final days of the summer window. Carrick only needs a backup for Luke Shaw, not an immediate replacement. The "English Carlos," who turns 31 soon, has one year left on his contract and will remain the first choice next season.

Luke Shaw was not included in England's 26-man World Cup squad, so he can participate in a full pre-season training camp this summer to ensure he is physically fit and healthy. During pre-season, Carrick will also evaluate two 19-year-old left-back prospects from United's academy: Diego León and Harry Amass.

The Manchester Evening News reports that León will join the first team for pre-season. After the friendly matches, the club will decide whether to keep him or send him elsewhere. United signed the Paraguayan from Cerro Porteño last year for £3.3 million, with add-ons potentially raising the fee to £7 million.

But León has yet to make his senior debut; he was assigned to the U21 squad for development. Apart from the first four games of the season, he hasn't even been named on the first-team bench. Now he must impress Carrick during pre-season to determine his future. With 12 United players away at the World Cup, there are plenty of first-team spots available, so young players will fill in. León made his Paraguay senior debut last season but didn't make the World Cup squad.

If it's decided that he is still not ready for the first team, United will consider loaning him to a Championship club for more game experience. León's rival, Amass, was loaned out twice last season. The English youngster, once hailed as the "new Luke Shaw," initially performed well at Sheffield Wednesday, scoring one goal in 21 appearances. However, with the club already relegated, United recalled him and loaned him to Norwich. At Norwich, Amass was unlucky, suffering a serious injury that ended his season early.

Amass will also join United's pre-season training. His challenge is greater than León's. If he fails to convince Carrick to keep him, United may loan him out or even sell him outright, using the proceeds to help fund the signing of a new left-back.
