The Gunners come to White Hart Lane for a third round tie in the Capital One Cup – and there must be a winner on the night.
Extra time and penalties will be brought into play if the scores are level after 90 minutes.
But, whatever happens, centre-half Jan says we’re in good shape going into the contest having won our last three consecutive matches in all competitions.
“It’s a big game against Arsenal – it’s a very important one, as it always is,” said the Belgian international.
“We have to keep this momentum going now and we want to beat them.
“We’ve kept three cleans sheets on the bounce before this game, which is great – we are learning more and more to play alongside other.
“The forwards are working well, Dele (Alli) and Eric (Dier) in front of the back four are working very hard too and obviously Hugo (Lloris) is class.
“Once you get one clean sheet you build confidence and that’s exactly what we’re doing.”
As for our line-up against the Gunners, Jan believes that whoever starts for us will be more than capable of carrying on from where we left off against Crystal Palace in the Premier League on Sunday.
“The gaffer may change it up – you never know – but after this game it’s City, Monaco and Swansea so we have to make sure we find the right balance,” he added.
“We started off very well against Palace and we continued like that for 90 minutes. I think we were the better team throughout the game.
“They were dangerous, twice hitting the post and forcing a great save from Hugo, but I think we played very well and looked very solid so we’ll be looking to carry that sort of thing on against Arsenal.”
