Sheffield United are reportedly one of two Championship clubs monitoring Manchester United winger Ethan Ennis, with Preston North End also linked with the 21-year-old. According to ontheminute.com, Preston North End are monitoring the youngster. Ennis spent this season on loan at Fleetwood Town. Several other unnamed clubs, including a number from the Championship, are also said to be monitoring the attacker. A transfer would most likely be a loan, as Ennis is reportedly highly-regarded at Manchester United, though a permanent deal valued at over £1m including performance bonuses is not ruled out.
