Former Tottenham captain Graham Roberts says they have failed to replace their sold stars.
"Last season you had the excitement of Modric and Van der Vaart. They are world-class players. Dempsey and Sigurdsson, are not.
"I've watched Spurs and, yes, they are open. The full-backs get forward but the midfielders come very deep now and get the ball off the two centre-backs. They are more regimental now.
"Van der Vaart last year got us out of trouble with so many second- half goals. I look at Dempsey and is he going to get you that? And Sigurdsson, is he going to get you that? For me, the answer is no."
