Caoimhin Kelleher is considered a significant upgrade for Manchester United as well. However, the likelihood of Liverpool selling to Manchester United is extremely low due to their historical rivalry. John Aldridge remarked that even though Kelleher would be an excellent fit for Manchester United, a direct transfer between Liverpool and Manchester United is highly improbable. Kelleher, who has consistently impressed when standing in for Alisson and has been a key player in Liverpool's League Cup matches, is expected to depart Liverpool at the end of the season following the arrival of Giorgi Mamardashvili from Valencia. Despite his ambition for regular first-team football, a direct transfer to Manchester United remains unlikely, with Phil Chisnall being the last player to make such a move in 1964. Aldridge also observed that while Kelleher deserves to be a regular starter and would improve any Premier League team, his future is more likely to be abroad or at a top European club.
