Everton boss Marco Silva has put Nathangelo Markelo on notice.
The Dutch teenager signed for Everton in the summer of 2017.
"We will see," Silva said, on the prospect of him being named in the squad.
"In the last match I had (Tyias) Browning on the bench.
"We have just 17 players in the squad list and so I called Browning. It could happen. We have more than 20 players working in the under-23s and if I need them they are there to play and help the team."
