The transfer mill is churning once again, with Man Utd believed to be lining up a move for Ousmane Diomande, the defender from Sporting. Sources close to the club suggest they are exploring options to reinforce their squad ahead of the run-in. While Man Utd and Sporting continue talks, no breakthrough has been reported. Chelsea, Liverpool and Crystal Palace reportedly may still have an interest, but currently the focus is on getting this deal across the line. Across the season 25/26, Man Utd have let in 20 goals in 13 (1.54 per game), roughly in line with the Premier League average. Ousmane Diomande would be expected to give them some extra stability and depth for the tougher stretches of the season. Man Utd have recently been linked with Neymar, Harvey Barnes and Valentino Livramento while Sporting have had no rumoured targets. Can't get enough Man Utd transfer rumours?
