Talent is not free. Wenger simply did not have money to spend after 2002, first, because of the drain of the new stadium, then because Kroenke ran the club like a Je........,like a miser.
If anybody thinks this will change under a new manager, you are in for a rude shock.
The only thing that changed was that Wenger’s scouting network was gradually broken up and his eye for talent started to diminish, partly thanks to the incompetence of Ivan Gazidis, who must be the most incompetent Chairman in The EPL.
