I think the competitive advantage we had in the market with Wenger evaporated as scouting networks improved. By that, I mean I think we benefited a lot from his extensive connections in the game, which enabled us to poach rough diamonds before others became aware. That loss of competitive advantage was one of the reasons I think Wenger suffered in his later years.
On Ade, easy to forget that a large proportion of the fanbase didn't rate him for his first 18 months or so. He also had a pretty awful track record in terms of goalscoring at Monaco so not sure TA is comparable. That being said, I'm not advocating we sign TA, just don't think the two situations are comparable.
