The 26-year-old had already been linked with a move to Old Trafford following a standout World Cup, and Brazilian outlet RTI Esporte now provides further detail on United's work behind the scenes, reporting that the Premier League club have made initial contact to assess a potential transfer.
Manchester United are said to have tracked Gill since the start of the season, with their observations intensifying significantly after his performances at the tournament.
United's recruitment department is understood to value Gill's physical presence and ability when dealing with crosses, along with his distribution and the composure he showed in high-pressure matches. A goalkeeper is considered one of the club's priorities in the current window, moving Gill higher up their list of targets. He is viewed by the Brazilian outlet as a player capable of taking on a prominent role in European football.
While previous reports had already placed Gill on United's radar, RTI Esporte's claim that preliminary contact has taken place marks a step forward in the club's interest, even if there is still no suggestion of a formal proposal being tabled.
San Lorenzo, for their part, appear resigned to the growing European interest in their goalkeeper, having reportedly accepted that resisting offers for much longer may prove difficult given the scale of attention his form at the World Cup has generated.
Gill has emerged as one of the standout performers of the tournament in the eyes of many European scouts, with his shot-stopping and command of his area helping Paraguay progress further than many had expected. That exposure has significantly raised his profile beyond South America, with United understood to see him as a viable option to add competition and depth to their goalkeeping department heading into next season.
For now, discussions remain at an early stage, with no formal offer yet on the table and San Lorenzo continuing to weigh up their options as interest in their goalkeeper builds across the continent.
