Rumours are swirling around Ousmane Diomande, with Arsenal reportedly showing interest in the defender currently plying his trade at Sporting. With both teams looking to strengthen their squads, the move could have a massive impact on their seasons going forward. Paris SG, Man Utd and Chelsea may look to intervene if talks continue without resolution. Arsenal's back line has been a real strength this season, conceding just 0.67 goals per game (14 in 21). Ousmane Diomande would be expected to slot into that unit and hold his own in an already solid setup. Sporting have also been linked with Luis Guilherme Lira dos Santos while Arsenal are reportedly monitoring Igor Tyjon, Bradley Barcola and Konstantinos Karetsas.
