The Portuguese coach has been installed as the new White Hart Lane boss, and has been given money to spend, with Gylfi Sigurdsson and Jan Vertonghen already signed this summer.
Chelsea midfielder Lampard feels his former trainer has a big job ahead of him in north London.
“AVB has inherited an exceptional squad of players,” Lampard confessed to The Sun.
“A squad that’s good enough to bring Champions League football and contend for the Premier League title. A team that’s played some terrific, thrilling attacking football and scored goals for fun.
“So AVB is a lucky man taking over at Spurs because the players are so very good.
“Admittedly that can be a double-edged sword, though, because Harry Redknapp will be an extremely tough act to follow.
“Harry lifted Spurs to an amazing level. The way he turned that club around was remarkable. They were at absolute rock bottom when Harry came in.
“Then all of a sudden they’re playing in the Champions League and competing at the very top. So he did an incredible job there and he definitely didn’t deserve to lose his job.
“That’s why I was really surprised when Harry left. He did wonders at Tottenham and I thought him leaving was a terrible shame,” the England international concluded.
