Dominic Ball - Tottenham Hotspur
Ball, 21, had been at Rangers last season and helped them win promotion to the Scottish Premiership.

The Express reported earlier this summer that Rangers were keen on trying to sign Ball on a permanent basis, and it is a disappointed for the Light Blues to miss out.
Perhaps more galling is the fact that Rotherham are managed by ex-Celtic defender Alan Stubbs, who took the Gers on as Hibernian boss last season and was beaten to promotion, but got revenge as they beat Rangers in the Scottish Cup final in May.

Ball started for Tottenham in pre-season against Juventus but did not impress, and with the high standard required at the Champions League side, it is not a surprise to see Ball move on.
Here is a look at how Rangers fans reacted on Twitter...
