Arsene Wenger believes Leicester City's early performances in the Premier League will serve as a warning for his side ahead of Sunday's game.
The newly-promoted side twice came from behind to secure a draw at home to Everton on the opening day and produced a battling display at Chelsea on Saturday before eventually losing 2-0.
The Foxes had the second best defensive record on their way to the Championship title last term and Wenger is preparing his side for a stern test.
"They are good at counter attacking, they have two good players on the flanks as well who are very quick"
"They have been impressive in their first two games," Wenger said. "They had a very good result against Everton and not only did they get a good result but they came back which showed mental strength as well.
"At Chelsea, they played very well. I have seen the report [on them] at Chelsea. It is a team who has very good defensive solidity. They are good at counter attacking, they have two good players on the flanks as well who are very quick.
"It is a team with a lot of threats. I think they have just bought two players as well. They bought Cambiasso from Inter Milan who is a very good, intelligent player so they will be a big challenge for us."
Sunday will be the first time the clubs have met since 2004 but Wenger will always hold recollections of one particular game against Leicester, at Filbert Street in August 1997.
"I remember two things; the first was a sensational goal from Dennis Bergkamp and my first experience with Ian Wright when I took him off and he didn't understand why," said Wenger. "I wanted to spare him some minutes at the end of the game. I think we were caught back and played 3-3 or something like that.
"I've many times said that Dennis Bergkamp scored one of the greatest goal I've seen in my career on that night."
