Spurs' victory over Everton leaves them level on points with second-placed Manchester United in the Premier League table, and with a real chance of catching leaders Manchester City.
"Can they win the title? A lot could still go wrong but they don't have any European distractions and they have the strength in depth they need," Hansen told BBC Sport.
"If they can keep players like Modric, Adebayor, Gareth Bale and Aaron Lennon fit, then they have got a real chance."
Tottenham will look to continue their run of form when they face Wolves on Saturday afternoon.
