After a completed medical and final agreement on terms, Matt O'Riley has been unveiled as a new Brighton signing. The midfielder leaves Marseille to embark on a new chapter - with fans of his new club keen to see what he can do. Brighton identified him as a top target early in the window and are said to be delighted to finally get their man. Interest had been high throughout the window, with Marseille and Juventus previously linked. But Brighton acted decisively, beating the competition and finalising all formalities to make him the latest addition to their squad. So far this season, Brighton are steady at both ends (1.42 goals scored per game, 1.33 goals conceded per game). The role for Matt O'Riley would be to keep that balance while lifting performances across the pitch. Marseille have also been linked with Nnadi Tocukvu, Souffian El Karouani and Ethan Nwaneri while Brighton are reportedly monitoring Charlie Cresswell. Looking for Brighton transfer rumours?
