In the immediate instance you may have, but as we lost and drew games we should be winning due to Bale no longer being there to score last minute screamers and keep us high up the league table, you and pretty much everyone else on here would eventually start to scream for him to be re-instated. This didn't happen with Ade because obviously he's not Gareth Bale and no one expected him to perform this way. However the fact remains that once he was re-instated, he's scored goals for fun.
I'm not sure he did say that. According to AVB he said 'He wasn't happy, he was disillusioned with his role in the team'. That doesn't sound like 'help me improve my game' to me. Again, you are assuming that you know what 'ideas' Ade was talking about. We don't know what they were, but everyone is assuming they are something along the lines of 'I'm Ade, I'm amazing, make me the main man'. No one has any idea.
Unfortunately AVB's job should have been to build Spurs into a club that could punch even further above his weight. In reality (wrongly on Levy's part IMO), his job was to get us into the top 4 this season. If he understood this to be his job, he stood a much better chance of succeeding with Ade in the team. I would have liked to have seen him put a little more effort into making it work. However, that being said, I do respect him for standing his ground if he truly felt what Ade done warranted the reaction he gave him. I'm just not sure it did.
Equally, maybe he didn't understand that this was his job as Levy may not have made it clear/shifted the goal posts half way through. If this was the case, then Levy is to blame.
