Tottenham's new goalkeeper Antonin Kinsky will "embrace the challenge" of dealing with Arsenal's set-pieces, according to Ange Postecoglou, who says the 21-year-old's confidence is rubbing off on the whole team.

Kinsky has kept clean sheets against Liverpool and Tamworth in a whirlwind start to his Spurs career since joining from Slavia Prague 10 days ago.

The Czech is set for his Premier League debut at the Emirates on Wednesday against Mikel Arteta's set-piece specialists, who beat Spurs 1-0 in September thanks to Gabriel's goal from a corner. In total, Arsenal have scored 10 league goals this season from set pieces - the most in the top-flight.

Kinsky was assured against Liverpool in the Carabao Cup semi-final first leg last week before dealing with Tamworth's barrage of his area from dead balls and long throws in Spurs' extra-time win over the part-timers in Sunday's FA Cup third-round tie.

Asked how his newest signing would deal with Arsenal's threat, particularly from corners, Postecoglou said: "It’s more to do with mindset in that he’s prepared to embrace that challenge, and the challenge we found in the last game [against Tamworth] when we found out just how strong they are on offensive set pieces and the players they’ve got in terms of both delivery and execution.

"You need to be well organised but you also need your goalkeeper to play a pivotal role. So far what I’ve seen of him he’s embraced those challenges.

"It’s not easy going to a place like Tamworth and they’re throwing balls literally under the crossbar and you’ve got about 20 bodies around you.

"And as much as it’s about technical ability its more about mindset and tackling that and he didn’t shy away from it. That really helped us because it gives confidence to the players around him because they know if it’s in his area he’s going to come for it and they can focus on their job.

"It does give some comfort to the players around him if they see he’s handling it well.

"It means they can then focus on their own job and be a lot more clear-headed. If he was struggling to adapt to the way we want to play or challenges...

"We prepared for Tamworth and what they were going to do, we knew every time they had a throw-in in our half it was going to come in the box and how we’d want to deal with it. That’s great in theory but then you have to go do it.

“When he came out and dealt with the first two and caught them, the players around saw that he’s got this. 'If he’s got this, I’m going to make sure.' If he didn’t and there was uncertainty there it tends to filter through the whole team."

Kinsky was signed as long-term competition for Guglielmo Vicario, who has been Spurs' No1 since the start of last season, and he has wasted no time in making his case, with the Italian sidelined until late February following foot surgery.

Postecoglou believes it is more important for goalkeepers to settle quickly than outfield players, who have greater scope to feel their way into a new environment.

"It’s a more pivotal role," he said. "You understand the consequences of a goalkeeper not feeling comfortable because he’s usually required in key moments.

"As an outfield player, yes there are key moments. But there are also parts of the game where you can settle into it and find his feet and work his way through any issues. Whereas goalkeepers for the most part whenever he’s involved, whether with or without the ball, it’s a key moment.

"[Kinsky's] ability to fit in really quickly has helped us enormously."

Gabriel's header settled a tight derby in September, while Arsenal twice scored from corners in 3-2 win over Postecoglou's Spurs last season.

Postecoglou, who faced scrutiny for the way his side defended set pieces last term, believes his players are far better equipped to deal with Arsenal's threat today.

"It’s the evolution of the team," he said. "Last year, people were pretty simplistic in their outlook when I spoke about set pieces, that I didn’t care about set pieces and we didn’t have a set-piece coach so we didn’t work on them.

"We haven’t put more emphasis on it, we’ve changed a few things around the way we’re defending and it’s working really well for us this season. We’ve changed our set up a little bit, the players have embraced that and for the most part it’s been really good.

"When we played them at our place they scored a good goal and that was the difference. They’ve done that to a lot of teams but for the most part we handled the set pieces well and we will have to again. They’ve got good delivery which is always difficult no matter what your set up is.

"Declan Rice delivers a great corner and they’ve got some big guys so we’ve got to be ready for it."
