The Frenchman reportedly passed the first stage of his Everton medical at Finch Farm on Friday and the Blues had hoped he could have completed his deal before the end of the weekend. However, United wanted Everton to match their valuation of the player which has taken some time to agree.
Schneiderlin will now attend Finch Farm tomorrow morning to complete his medical and sign with Everton after already agreeing personal terms.
Schneiderlin rose to prominence following an impressive couple of seasons at Southampton, with a host of top clubs vying for his signature.
However, since his move to Manchester United, he has only made 32 appearances in two years and under Jose Mourinho has found his chances even harder to come by.
He will hope working under Ronald Koeman will revitalise his career.
