My first choice would probably be Callum Styles from Barnsley (Maybe put a £2m bid in?).
22 years old, Hungarian international, used to be a LM but played in the CM role last season - Can also play RM and possibly CDM.
I like O'Hare, Willock, Bowler, etc... but I think Callum Styles is the closest "like for like" replacement in terms of attributes.
Total wildcard, and he's definitely not as good as Tavernier... But I think we should throw £1 million in for Paddy Lane from Fleetwood too.
He's 21, played for Northern Ireland U21s with Boyd-Munce, and he was league 1 young player of the year last season.
He had 13 goal contributions in 37 games for a team which nearly got relegated. He can also play CDM.
We could also use the money we've got to build a younger squad for future seasons...
CB - Ronnie Edwards from Peterborough (19)
RWB - Alex Scott from Bristol City (18)
LB/CB - Shadrach Ogie from Leyton Orient (20)
CM/CDM - Jordan James from Birmingham (18)
CM/CAM - Finn Azaz from Plymouth (21)
Loads of championships clubs do it every season, and have done it this summer.
Huddersfield just signed Jack Rudoni from Wimbledon for 800k.
