Arsenal youngster Ainsley Maitland-Niles will now complete his season-long loan move to the Blues on Thursday, TWTD understands.
The 17-year-old has been at the club today for a medical and the paperwork relating to the switch will be completed on Thursday when he will train with his new team-mates for the first time.
Speaking at this morning's press conference, manager Mick McCarthy said he sees Maitland-Niles as a versatile midfielder, who "can play anywhere along the midfield".
Goodmayes-born Maitland-Niles joined Arsenal’s academy aged nine and broke into their U21 side during 2013/14, signing a pro deal in October 2014.
The England U17 and U18 international made his senior debut as a sub last season in a Champions League game with Galatasaray and also made first team appearances from the bench against Newcastle in the Premier League and Hull City in the FA Cup.
Maitland-Niles hit the headlines earlier in the year when his mother, Jule Niles, was arrested on suspicion of assaulting two people at Arsenal’s training ground, amongst them Arsene Wenger's negotiator Dick Law. She was later released without charge.
