What are you talking about?Surely assessing them now is more beneficial and will give him more time to determine the needs of the squad? He will see more in the next 10 games in terms of mentality and ability than he would in preseason as its actually competitive.
He can explore the transfer market now. Doesnt have to wait until the summer.
Pre-season would give JN 6 weeks to explore everything from fitness testing, through to tactical analysis. He’s not going to be doing that now with 10 games to go, is he?
How is he going to explore the market now? It’s closed! Come the end of season he’ll be able to dip in & out, fine tuning a squad to play in ‘his way’.
In pre season JN can rotate his squad and try new formations which suits the current squad and players he has eyes on. He could arrange a friendly every day if he so desired. He won’t be able to do that now will he?
Surely you can see the merits of waiting if you were in his shoes? Astounded you’d think otherwise tbh.
