I refer to my comments posted in December last year :

"I have seen Olise in recent matches.
Can play out wide or in the middle of midfield and even as a striker but he is mainly deployed as a midfielder.
Is left-footed, easy on the eye and whilst he doesn't possess searing pace he is sufficiently fleet of foot to cause problems for the opposition.
He provides good delivery at set-pieces, is creative and works hard off the ball.
Certainly not the finished product but he is still in his teens and is certainly a good prospect."

I'm also going to defer to what I said earlier in this thread in December.

A very exciting prospect, that will ad strength in depth to the squad, a great option to have at a young age and potential to develop further. In this day and age a bargain at 8 million and worth any risk. Exactly the sort of signing we should be looking at.

Very happy if we get this over the line.

That in its self might prove a problem. I just hope this hasn’t come out to soon. If the the player isn’t already on board this could turn into another frigging auction. This kid is definitely a prospect, that we are not the only ones aware of.

I am hoping that this young French midfielder will have been attracted by the opportunity to play for one his country's greatest ever midfielders. He will probably want to move on to greater things in due course but may see PV as the ideal person to help him get to the next level.

This was posted yesterday, it would appear (hopefully) that it is completed

Why does every deal we do take sooooo long to finalise and then collapse at the 11th hour?
