#6 James Chester (Aston Villa) – £6.0mEmbed from Getty Images
Chester joined Midlands rivals Aston Villa for an initial £6m fee in 2016 following an impressive string of performances for Wales in the European Championships that summer.
Tony Pulis was happy to let him leave as Chester was mainly a backup defender and once he began complaining about his lack of gametime, it was probably only fair to let him try and play football somewhere else.
#5 Shane Long (Hull City) – £7.0mEmbed from Getty Images
Shane Long signed for Hull City in January 2014 for an undisclosed fee, although it was understood to be a deal that could rise to £7m — and many suspect it soon did.
The Republic of Ireland forward bagged 22 goals in 87 games for the Baggies during the three seasons he was with them.
West Brom’s sporting director, Richard Garlick, claimed that the club had offered Shane Long a new deal on two separate occasions, and that it would have significantly increased his salary; but clearly, he had his heart set on leaving before the end of the window.
