I bet Fofana's pilot is chuffed to do a handbrake turn a mile off the ground.

Crystal Palace are attempting to hijack Sunderland’s move for Lyon’s Malick Fofana.
The winger had agreed to join Sunderland in a deal worth €35m - but Palace have made their own proposal.
It is now up to the player to decide.
Image source, Getty ImagesI’ve seen a little of Fofana playing for Lyon and he looks a talent. Got a good eye for goal and so far been able to produce in the league and Europe. As an Arsenal fan, gutted if he does to Sunderland and we didn’t get this over the line.

Well, Simon, he might not be heading for Sunderland after all...
Arsenal have been too passive this transfer window. The replacements for departing/injured players has been fine, but in no way has the squad been improved. Not a happy Gunner.
Barry
Arsenal fan - we're in trouble here. Our left side is now shot, no replacements; morale will drop, plus we have Chelsea flying high on signings and results on Sunday. That's got a Chelsea win written all over it. Something big better happen today for us.

Everton are working on a £5m Euro deal to sign the former Arsenal defender and midfielder Ainsley Maitland-Niles from Lyon.
The deals comes after the Toffees had a problem with the securing Kenny Tete from Fulham.
Everton had agreed a £9.4m deal for Tete but it seems Fulham are having trouble lining up a replacement and they won't sign off Tete until they do.

As a Villa fan, I think we have made some smart signings in reducing the average age and wage bill of the squad. Once the window finally closes and Unai can work with a settled squad I think there is reason to be optimistic for the future! UTV

Brilliant signing for Villa, Mbaye, Madjo and Manzambi all waiting to go. Who needs MSN when you've got MMM.
