Everton made a last-minute addition on transfer deadline day with the loan signing of Belgian teenager David Henen.
The 18-year-old had been training with the Toffees until recently but his parent club Anderlecht decided to sell him to Greek side Olympiakos on Monday.
However, Everton struck a deal to bring the youth international back to England for a season-long loan, although the paperwork was not completed until very late in the day.
Everton manager Roberto Martinez has confirmed a deal is close for Anderlecht teenager David Henen as the Spaniard looks to bolster the club's youth ranks.
The 18-year-old Belgian will go into the under-21 squad once his reported £1.5million move has been done.

It is in the process of being completed.
He's a young, talented footballer who represents Belgium in the lower teams, in the under-18s and has had good experience in going to France.
He is a bright boy and we feel he is something different that we haven't got in the under-21s so we are hoping he is going to be giving us something different in that group.
We want a strong group. We have already got talented and very interesting footballers and I think David can fit in really well in that environment.
Anderlecht midfielder Lucas Biglia hopes to finalise a move to Lazio "as soon as possible".

Everything is done with Lazio. I can't wait to get to Italy, I'm just waiting on the all-clear from a medical.
I hope to be there as soon as possible. I'm ready to impress and Lazio is the perfect club for me.
I've won everything in the Jupiler League and so moving to a superior championship is the next logical step.
Most of all it's a move that boosts my chances of getting into the national team for next year's World Cup in Brazil.
