Of course you can count him, he played all last season and I am sure AVB was in contact with him from the minute he arrived because no doubt Levy was 90% sure he would be s Spurs player again this year. Other than that I agree with all else you've said above.
Obviously AVB is trying to improve the team. All I am saying is, with the players that he currently has, the minimum we should expect is to challenge for a CL spot, even more so if he makes some good signings.
To me, folks are implying that it's ok to finish outsite of the top 4 because AVB is building for the long term. What I am saying is if we don't at least challenge for it all our best players will go to pastures new and the building process must start from scratch again. To me, we are at a pivotal point here, we either push on from this season, finish in champions league, sign world class players and go on to challenge for titles (if we put up a good challenge for CL we may hold on to some for maybe one more season) or we don't, lose all our best players and have to live with another few years of mid tableness before we ever reash these heights again (if we ever do).
AVB has said himself, he wants to build on what we already have here. Losing our top players is not the way to do that.
