Rumours are swirling around Marc Guehi, with Barcelona reportedly showing interest in the defender currently plying his trade at Crystal Palace. With both teams looking to strengthen their squads, the move could have a massive impact on their seasons going forward. Atletico, Man Utd and Bayern Munich remain in the background, but for now, Barcelona are leading the way in ongoing talks. Barcelona's back line has been a real strength this season, conceding just 1.05 goals per game (20 in 19). Marc Guehi would be expected to slot into that unit and hold his own in an already solid setup. Crystal Palace continue to be linked with Kevin Danois, Joao Gomes and Ilan Kebbal while Barcelona are also rumoured to be tracking Mickey van de Ven, Alan Godoy and Igor Vinicius.
