Diego Leon, United's first player to sign since Amorim took charge, will fly to Manchester in the next few days to visit and complete a medical examination. The 17-year-old Paraguayan left-back is unable to join directly and will have to wait until he turns 18 in April to sign a contract, so he didn't really become a Red Devils player until July this year.

Leon's agent has confirmed that the defender will soon undergo a medical at Manchester United. Renato Bitar told local reporters that he and León will travel to Manchester in the coming days, where the player will undergo a medical examination. Once Manchester United officially announce the transfer, León will become the first Paraguayan player in the club's history.
León only made his debut in Paraguay's top flight for the Portno Hills in August last year, and by October he was already able to link up with Premier League giants such as Manchester United and Arsenal. In December, United spent £5 million to sign him. Italian transfer expert Fabrizio Romano has confirmed that Manchester United have signed all relevant documents with him.
Not only does the left-back not look like a 17-year-old, but he also has an incredible physique compared to his peers. He is strong in individual confrontation and defence, and at the same time, he is very dangerous in terms of assists, having scored two goals in 19 games, and is widely regarded as one of the most promising young players in South America at the moment.
Leon's move is in line with Manchester United owners Sir Jim Ratcliffe and INEOS's buying strategy of bringing in young, talented and successful youngsters and developing them into world-class superstars. However, his arrival could lead to the departure of one of the existing Academy players, with 17-year-old England left-back Harry Armas being disappointed not to play so far and may be looking to leave. It is reported that Leicester City, coached by former Manchester United assistant manager and interim manager Ruud van Nistelrooy, was interested in bringing in Armas on loan from Manchester United in January.

Leicester City are currently in the relegation zone and Ruud van Nistelrooy says he will use his 'network' to bring in a number of players in the winter window, including Manchester United. In addition to Armas, Manchester United centre-back Victor Lindelof and midfielder Toby Collier are also targets for Ruud van Nistelrooy. However, according to the rules, Ruud van Nistelrooy can only take one loan from Manchester United.
Asked if he would use his connections at Manchester United, Ruud van Nistelrooy said: "I'm looking into my network because I've played in a couple of leagues. It's important to use this to strengthen the squad and help the team achieve their goals. But it's better to look at the injuries first and then draw conclusions and we'll decide what to do. Leicester need reinforcements to strengthen the squad."
Armas moved to Manchester United from Watford in 2023 and was promoted from the under-18 to under-21 development squad last summer, where he was part of the first-team training camp and was one of the standout performers in pre-season. However, despite his favourite views on him as manager at the time, Ten Hag never used the young left-hander in official matches.
Amorim didn't have a left-back in charge, but Armas didn't use it either. England's 'New Luke Shaw' has been named to the tournament five times this season, all of which ended in disappointment. Leon's signing indicates that the club is not as optimistic about Armas as rumored. According to rumors, well-known left-backs such as Jorge Mendes of Paris Saint-Germain are also on the list of future reinforcements.

As a result, Armas could choose to leave Manchester United on loan or even on a transfer, with his contract expiring in 2027, and not only Leicester City, but also Aston Villa and Championship sides are eyeing him.
