I agree, even if he canot change everything in one go he should be doing it little by little in EVERY window
Yep. Yhat's been my view for a long time. We don't have the power to go and get whoever we need, whenever we need. Hence, someone at the club should be planning well in advance for every transfer window with a view to buying and selling to make even the smallest of improvements.
e.g. Lucas and Moreno add nothing to the team, even as back ups. I understand Lucas is a great professional('servant' if you wish) ... but that shouldn't be enough for us. they should've been off the payroll over last summer thus freeing up budget for better palyers.
