Ian Wright says if Tottenham's form dips later this season, they could have serious problems.
The season is still early though, and as he notes, there is plenty of time for Spurs to crumble, and suggests if they do then it may be something they struggle to correct in the future too.
He said: "This is a different Spurs, its not the same Spurs. The players are getting it. They look fitter, they look stronger, they've got everything in every department.
"Now we will see if under Pochettino if they can dispel myths of 'can they do it a bit and then fall to pieces?'
"This is the team, if they still falter and go into typical Spurs then this is something which is endemic forever with them, which isn't something I'd say I wouldn't want to happen, but there's a different vibe about them."
Wright is suggesting a mentality of doubt at Tottenham, and it's correct that they have dropped from strong positions late in recent seasons to miss out on the top four positions, but it has been about more than that.
Recent failures have been just as much to do with squads having a lack of depth, and Tottenham failing to spend in January from a position of strength.
This is a mistake the club cannot afford to repeat, especially in the striker department so they have strong alternatives to Harry Kane in attack.
