Here’s nine alternatives the Blades could target in the summer transfer window...
1. Alex McCarthy - Southampton
Now Angus Gunn is the main man at Southampton, Alex McCarthy needs a move to secure regular first team football. He's a top stopper, and could be a fine acquisition for the Blades. (Photo credit: GLYN KIRK/AFP/Getty Images) Photo: GLYN KIRK
2. Darren Randolph - Middlesbrough

3. Sergio Romero - Manchester United
If United want to give Henderson a crack, that's bad news for Sergio Romero. Wages would no doubt be a problem, but with 96 caps for Argentina, what a signing he'd be. (Photo by Gareth Copley/Getty Images) Photo: Gareth Copley
4. Freddie Woodman - Newcastle United
Another England U21 international, Freddie Woodman has bags of potential, and plenty of top sides are on his tale. He'd certainly be worth a crack, though perhaps on loan at first. (Photo by Jan Kruger/Getty Images) Photo: Jan Kruger
