Manchester United have been making waves recently as they continue to be linked with an ever-expanding list of players. It is no surprise since they are one of the wealthiest clubs in the world and are looking to improve after their Europa League loss to Villarreal.According to the Daily Mail, the Red Devils have chosen to prioritize Jadon Sancho as their summer transfer target. Ole Gunnar Solskjaer prefers a move for Sancho over Harry Kane, who is thought to be leaving Tottenham this summer following hints he gave in an interview.Manchester United have successfully qualified for the Champions League and therefore they will be confident in the transfer market. They did lose the Europa League final, though, so they are in need of some new players to strengthen their backbone.Manchester United must act quick to avoid overspendingThe Euros are fast approaching and Jadon Sancho has been featured in England's provisional squad.
