The Lennon situation is going to be interesting.
In AVB's formation, the guy on the right of the 3 is usually the one that will cut in and contribute more goals. This doesn't suit Lennon. Bale on the left could keep the width, or they could tweak it so that Bale is the one cutting in and Lennon is the width-keeper, and even though Bale has shown (like against Chelsea in 09/10) he can cut in from the left and score, I think in general it works much better if he's cutting in to shoot and have the natural angle to do so with his stronger foot, meaning he would be better on the right. I really think he would be utterly devastating in that position.
But then it begs the question, what happens with Lennon? If Bale is played as the width-keeper on the left, Lennon would need to be the goal getter on the right. Maybe we could swap them, so that Bale cuts in from the right and Lennon keeps the width on the left? From how it seems, the width position is to stretch teams and therefore it's the starting position that's important. So Lennon could start hugging the touch line on the left, and then cut in, potentially getting goals himself. It may be that because the starting position is important, the formation doesn't require someone to get to the byline and cross, it just requires someone capable of holding the width and being an outlet. If we had the play on the right, with Bale cutting in, Walker on the overlap, Siggy supporting and Ade looking for the ball in the box, and Lennon is holding his position in the left, if we could switch the ball to him quickly he would probably get a fair amount of one on one opportunities to skin his man, cut in and score himself.
But if he isn't intended to be used like that, I do wonder how he will work. If he's the width keeper on the right, Bale could need to cut in from the left, which he can do but I feel he wouldn't have the angle to be totally effective. Maybe we will be able to tweak it in a lot of different ways this season. Occasionally Lennon is the width keeper on the right, and Bale cuts in from the left, occasionally they are swapped, and occasionally maybe we have an Oscar or even a GDS (who has said he will happily stay with us if no offers come in...I think he's either spoken to AVB or realised he could be effective in his system) coming from the right, and Bale as a width keeper on the left.
