Glasner i think is wise enough to know he cannot play the counter attacking football with a top side, the fans wont except it, it only works when the opposing team is attacking you, same team vs Vila and the Norwegian side, one attacks, one defends, we go from woeful to world beaters in three days, Palace is the perfect club for him, tolerant fans, low expectations, mostly playing against teams that attack, that is why we probably will struggle against Sunderland, unless we get an early goal, and Glasner wont change his tactics for any club, he will change to the club that matches his tactics.
