Fast-starting Foxes have two wins in two under new boss Claudio Ranieri.
Mousa believes we deserved more than one point after our performances against Manchester United and Stoke and says the lads are determined to get a win in the bag at the KP Stadium.
“Leicester have good individuals and as a team, they perform well,” said the midfielder.
“We are Tottenham, we believe in our quality and we have a lot of quality here in this group.
“Of course, we don’t underestimate Leicester in any way. It won’t be easy but if we’re all 100 per cent we have a good chance.”

Reflecting on the 1-0 loss at Old Trafford and 2-2 draw against Stoke, where we led 2-0 only to be hauled back late, Mousa added: “I don’t think it’s a case of not performing well.
“In fact, the first half display against Stoke was better than a lot of games last season. That’s positive and it’s a shame it ended negatively.
“Leicester are in a good flow but if we play like we did against Stoke over the 90 minutes we’ll have a good chance against any team.”
