Arsenal overcame a tough Turkish test in midweek to qualify for the Champions League. Alexis Sanchez's first Arsenal goal split the Gunners and Besiktas. Arsenal haven't hit top form yet but they remain unbeaten and have gained confidence after beating Besiktas. Arsenal have shown character in their previous two Premier League games and if they can continue their good form then they will definitely be favourites against Leicester. Also with influential midfielder Aaron Ramsey back, Arsenal will be relishing a match against one of the new promoted sides. 

Leicester's form is the complete opposite of Arsenal's. Leicester are winless in all three games of the season, drawing against Everton and losing against Chelsea and Shrewsbury. The Foxes would be desperate to beat Arsenal for the first time in nearly 20 years to kick start their season. Arsenal look like a much stronger team when Ramsey plays and he is a goal threat. On the other hand, Ulloa has been in good form and may continue it against Arsenal. 

Team news:

Aaron Ramsey returns for Arsenal after serving his one match European ban, but Kieran Gibbs, Mikel Arteta and Oliver Giroud are all out. With Giroud out Sanchez will most likely start up front. Long term absentees Gnabry and Walcott are still out. David Ospina is close to recovering from a thigh strain that he picked up during the World Cup. 

Esteban Cambiasso could make his Leicester debut this weekend after signing a one year deal with the club on Thursday. He was registered just in time to be eligible for the game. Also, the first team players that were rested for the Foxes midweek League Cup game will all be recalled. Vardy, James and Drinkwater will all be assessed before Sunday's game. 

Match stats: 

Arsene Wenger has never lost a Premier League match against Leicester. 

Leicester lost one against Arsenal in November 1994. That is their only Premier League win against the Gunners (Played:16 Won:1 Drawn:5 Lost:10). 

Arsenal's last game against Leicester was the final game of their Invincible season.  

Leicester have won only one of their last 14 home Premier League games, but has the best home record in the Championship last season.
