Manchester United are preparing for a Champions League encounter against Atlético Madrid, but ahead of another major European fixture on the 12BET Malaysia calendar, an unexpected development has emerged at Carrington involving Brazilian midfielder Andrey Santos. The summer signing reportedly left the training ground separately from his teammates, raising uncertainty over whether he will travel to Spain. Although his participation remains unconfirmed, the bigger concern is how quickly his promising move to Old Trafford has turned into a frustrating experience.

Santos arrived from Chelsea during the summer transfer window for £50 million, with United expecting him to become an important part of their midfield rebuild. Instead, the Brazilian has accumulated just 16 minutes of competitive action since the season began. Following his involvement in the opening Premier League fixture against Hull City, he gradually disappeared from Michael Carrick’s rotation. For a player commanding such a substantial transfer fee, the lack of opportunities has inevitably raised questions about the club’s recruitment decisions.

Manchester United invested nearly £150 million in three midfield additions this summer. Santos and Youri Tielemans arrived first, followed by Carlos Baleba, who joined from Brighton for £70 million. Despite that considerable expenditure, only Tielemans has secured regular playing time. The other two recruits have struggled to establish themselves, leaving supporters wondering whether the massive financial commitment has genuinely improved the squad.

Baleba recently recovered from injury and made his United debut against Tottenham Hotspur. Although his performance lacked spectacular moments, his physical presence, work rate and willingness to compete impressed sections of the Old Trafford crowd. Tielemans has meanwhile emerged as the most dependable of the three midfield newcomers. Santos, however, remains the biggest disappointment, and the contrast has become increasingly apparent throughout the 12BET Malaysia football season. Spending £50 million on a midfielder who rarely leaves the bench hardly represents effective squad management.

The circumstances surrounding these signings make the situation even more complicated. Santos was neither United’s first choice nor their second option during the summer. The club initially pursued Elliot Anderson, Mateus Fernandes and Aurélien Tchouaméni, while another potential recruit, Ederson, reportedly failed his medical examination. After those attempts proved unsuccessful, United turned toward Tielemans and Santos as alternative solutions. Neither arrived cheaply, intensifying criticism of the recruitment department and its inability to secure preferred targets.

Nevertheless, writing Santos off completely would be premature. The Brazilian demonstrated considerable promise during his time with Strasbourg in Ligue 1, where his performances helped establish his reputation as an emerging midfield talent. His progress also earned recognition at international level through selection for Brazil. Leaving Chelsea was supposed to provide greater opportunities for regular football, allowing him to develop through consistent competitive appearances. Unfortunately, his move to Manchester United has produced the opposite outcome, with limited playing time threatening to interrupt his development at a crucial stage of his career.

United’s midfield difficulties are only part of a broader recruitment problem. Despite spending heavily on central players, the club failed to strengthen the left-back position during the summer. Luke Shaw has suffered another injury setback, while Patrick Dorgu is also unavailable, leaving Carrick desperately short of suitable defensive options. United previously considered signing Newcastle United defender Lewis Hall, but negotiations never progressed because of concerns over the transfer fee.

That decision now looks increasingly costly. With injuries reducing the available defensive options, Carrick has struggled to maintain a balanced lineup. The club’s failure to address an obvious vulnerability has compounded the disappointment surrounding its midfield investments. Reports suggest that Manchester United could return to the transfer market in January, potentially committing substantial additional funds to strengthen both midfield and defense if performances do not improve.

The uncertainty surrounding Santos and his possible involvement against Atlético Madrid adds another complication to United’s preparations. Whether he travels with the squad remains unclear, but his prolonged absence from meaningful competition has already exposed a troubling disconnect between recruitment planning and managerial selection. A talented international midfielder should not find himself effectively sidelined so soon after such an expensive transfer, particularly when the team continues to struggle for consistency.

With Manchester United facing a demanding series of fixtures across the 12BET Malaysia football calendar, the continued exclusion of Santos could turn his £50 million arrival into the most disappointing transfer decision of the summer. His potential remains undeniable, but potential alone cannot justify a major investment when opportunities to contribute are almost nonexistent. Unless Carrick begins integrating the Brazilian into his plans, United risk wasting both valuable resources and an important stage of the player’s development. The coming weeks may ultimately determine whether Santos can rescue his Old Trafford career or become another costly example of recruitment gone wrong.
