3. Will Hughes - Crystal Palace
Hughes had been linked with a move to Newcastle for a number of seasons and when he was reportedly frozen out of the Watford first-team set-up, it looked like a move may be on the cards. However, Newcastle never firmed up their interests and Hughes switched Vicarage Road for Selhurst Park. (Photo by George Wood/Getty Images)

4. Axel Tuanzebe - Aston Villa
Having worked with Steve Bruce previously, it looked like St James’s Park would be Tuanzebe’s most likely destination, yet, the Manchester United centre-back ended up signing on loan for Dean Smith’s Aston Villa instead. (Photo by Michael Steele/Getty Images)
