About the squad registration stuff;
At the moment we have 3 senior players (born before 1st January 2000) more than we're allowed to register for the 25 man squads for PL and CL, including 1 senior non-homegrown player more than we can register. So unless we want to make some players unhappy by not allowing them to play for us we need to get rid of 3 senior players before bringing in any more.
UEFA also requires 4 out of the 25 for the CL squad to be club trained (ie. only 21 non-club trained seniors), so if Ojo and Woodburn are among the outgoings we'd still need to offload two non-club trained players to be able to register all our seniors. That's before signing any new senior players.
Here's the full squad with HG-status for the upcoming season (made before Wilson exit) :
Edit: Just read up on the previous few pages here and checked the UEFA rules on player registrations, and it seems Elliott has to be registered on the A-list (senior players) for the CL squad. That leaves one less spot for non-club trained seniors.
