After selling Gareth Bale to Real Madrid for a world-record fee this summer, Spurs spent big on a revamped squad and sit fifth, three points behind rivals Arsenal, in the Premier League table ahead of the Tigers' visit to White Hart Lane.
"This is the strongest Spurs side I can remember in all my time in football both as a player and manager," Bruce remarked to reporters. "I'm sure they have the talent to win the Premier League this time around.
"For them, though, it is all a matter of mentality and attitude. It is a question of 'have they got the mental strength to go and win it?' more than 'have they got the ability to finish at the top of the pile?'.

"They are now a very accomplished side - and, of course, they currently have the country's outstanding individual player in Andros Townsend.
"The ironic thing is that they have lost Gareth Bale to Real Madrid but are arguably a better and stronger team without him. They are a really top side now and Andre [Villas-Boas] has bought marvellously well.
"So, for me, it all depends on whether what they have got between their ears matches the talent they have in their feet."
Despite the formidable nature of Sunday’s foes, Bruce is optimistic that his Hull side can do the north Londoners some damage.
"We have proved already since coming up from the Championship that we have got the spirit, attitude and ability to handle playing in the Premier League," he added.
"We have put up a decent show so far and it is important that we maintain those standards. The challenge we are facing at Tottenham doesn't daunt us - it is one that we are looking forward to."
