Raphinha exploded onto the scene at Barcelona last season, scoring 34 goals and providing 25 assists in 57 appearances across all competitions.
His contributions to Barca's double-winning campaign have placed him among the favourites for the Ballon d'Or, alongside teammate Lamine Yamal, Ousmane Dembélé, and Vitor Roque.
Man United test Barcelona with Raphinha bid
Manchester United are looking to turn things around after a disappointing season and have made a bid for Barcelona star forward.
His outstanding performances have caught the eye of Manchester United, who have reportedly submitted a staggering £137 million bid to the Catalan giants, according to Sportal.
While Barcelona would prefer to keep Raphinha, a bid of this magnitude is difficult to ignore. A decision is expected in the coming days.
United have already signed Matheus Cunha this summer, with Bryan Mbeumo also nearing a move to Old Trafford.
The club are also searching for a striker, with Sweden's Viktor Gyökeres among the potential targets.
