Why is Marc Guehi allowed to play vs Liverpool in FA Cup despite featuring for Crystal Palace?

All you need to know about Marc Guehi's eligibility for the FA Cup this season: Eligibility: Marc Guehi can represent Manchester City in the FA Cup quarter-final against Liverpool. This follows a significant mid-season rule change by the Football Association regarding player eligibility. Cup tie rule: Previously, the "cup-tied" rule strictly prevented any player from appearing for more than one team in a single tournament season. However, the FA has updated these regulations to modernise the competition and provide greater flexibility for January transfers. Changes: The new legislation specifically allows players who have moved between clubs in the winter window to be registered for cup matches with their new employers. This change was implemented to ensure that high-profile signings are not forced to sit out the most prestigious domestic cup matches. Previous rounds: Guehi had already featured for Crystal Palace in the earlier rounds of the competition before completing his big-money move to City. Under the old framework, he would have been a spectator for the remainder of the tournament. A huge boost: The rule adjustment is seen as a major boost for elite clubs, who often invest heavily during the mid-season window to bolster their squads. City officials reportedly pushed for this clarification to ensure their new defensive star could participate, with him featuring in the City squad against Salford City and Newcastle in the fourth and fifth rounds, respectively. Naysayers of the ruling: Critics of the move argue that it potentially erodes the traditional integrity and unique "one-club" spirit of the historic knockout tournament. Nevertheless, proponents believe it aligns the FA Cup with other European competitions that have already relaxed similar restrictions. History of the ruling : It is the second time this season that Pep Guardiola's side have benefited from the rule. Antoine Semenyo played in both legs of the League Cup semi-final against Newcastle United after his switch from Bournemouth. Liverpool clash: The England international is now fully cleared to face Liverpool as City continue their quest for more silverware. This development ensures that the best players remain on the pitch for the season's biggest and most-watched fixtures.
