Despite the goals, which have moved him onto 105 in the Premier League, Kane has not looked his usual self and he missed a couple of simple chances against the struggling Hornets.
"Of course it is a mix about different things". I think it wasn't a great period for him the last few weeks.
"Coming here and creating that many chances, to not come away with a goal is a little bit disappointing", Mariappa said.
But the forward, who now has 27 league goals and 38 for the season, can cope with criticism as he tries to catch Liverpool's Mo Salah (31) for the Golden Boot as Premier League top scorer. 'Last year I got 29 goals so I'd like to beat that but we'll see what happens. He is a strong guy - physically and mentally. I am sure that, first of all, he will perform for us and no doubt he will arrive in very good condition for the World Cup.
It is almost two years since Mauricio Pochettino joked his side "do not exist" without Mousa Dembele but it is still hard to imagine Tottenham without the Belgian, who has been described as a "genius" by his manager.
He then produced a disappointing performance in the FA Cup semi-final against Manchester United, leading to an official FA Twitter account mocking him with a video that suggested Kane had been in Chris Smalling's "pocket" for the entire game. Maybe we didn't play the way we wanted to play and our performance wasn't right but most important was the three points. "To win the games and finish in the top four for the first time would be great for the club".
"A clean sheet for a keeper is so, so important".

Maybe she's born with it, maybe it's lies ", she added , referencing a cosmetics tag-line, "It's probably lies". Naysayers would have latched on to anything she said to taint the evening and Wolf's reputation.
"That [Raheem] Sterling tackle [in the Man City game], wasn't a penalty".
And Pochettino told Sky Sports: "I think it was a good night for us".
"Obviously, I would have liked to play better over the last few games or so but I think the whole team feel like that", said Kane. "Hugo is one of the best".
Spurs are also five points ahead of Chelsea having both played 35 times with the Blues set to visit Anfield on Sunday. It keeps us in a very good position in the top four, fantastic.
With less than two weeks until the end of the campaign, and a Champions League place very almost secured, Pochettino may decide to spare Dembele the matches against West Brom, Newcastle and Leicester City, regardless of whether he is available.
'I'm looking forward to the last three games, hopefully I can finish strong like I did past year and then obviously we're going into a big summer (with England)'.
