Arsenal boss Arsene Wenger recognises the changes in Leicester City's attacking tactics compared to the last time his side played them at the King Power Stadium.
The Gunners beat the Foxes 5-2 in the reverse fixture back in September, an open tie that had 43 shots on goal.
Speaking ahead of the match on Sunday at the Emirates, Wenger said Claudio Ranieri's side are a little bit cautious and do not play an open game like earlier on in the campaign.
"I don't defence after the game [in September], ‘I’m not happy with your performance’ because they created goal chances,” Wenger said, as Arsenal.com quoted. "We created many as well. It could have been, 5-2 or 8-4. I was already impressed by their offensive potential.
“But it was a very open game. I watched our game again because I wanted to watch how this team moved since then. There is an evolution in their game. They are more cautious at the moment. They play a lot in their final third and come out very quickly.
"Look at the number of direct balls from their half to the opponents’ half. They are higher than anyone else because they have Vardy on his way straight away when they win the ball - they do it very well. They suck you in and go very quickly in the opponents’ half. At the time they were a bit more all going. Today they are a bit more 'let’s sit here and use our strengths' in a very efficient way, which is what they did remarkably well against Manchester City.
"We will try of course to stop their counter-attacking. But at home you have to express your strengths and our strength is to have the ball. We have to try to express our strengths and as well try to stop them from hitting us on the break."
