Premier League 
After returning to the top of the league with their dramatic 4-2 win at Villa Park, Arsenal now travel to the King Power Stadium to face a Leicester side coming off the back of a disappointing trip to Old Trafford after seemingly finding form this season.
After 20 minutes at Old Trafford on Sunday, Brendan Rodgers would’ve thought he had found the formula for his team to reach the top half this season, with his new-look attack of Harvey Barnes, James Maddison, Tete and Kelechi Iheanacho creating chances at will and after scoring 4 goals in back-to-back games.
However, after not taking their chances and conceding first, they never got back into the game, losing 3-0, giving Rodgers more answers than questions, especially defensively, with his team without a clean sheet in 8 Premier League games since the restart, conceding 16 goals, the joint most in the league, which is not the best form to take into a game against the league leaders, who have already scored 4 past you this season.
Despite going behind twice at Villa Park, Arsenal got back to winning ways after 3 Premier League games without a win, with goals in the 93rd and 98th minute sending them back to the top of the league after losing it in the week against Manchester City.
Like Rodgers, Mikel Arteta would be worried about the recent state of his defence, with his side on a current of 5 Premier League games without a clean sheet, the longest of their season so far, in which they have conceded 9 goals as well, which is a massive fall off as they had only conceded 14 goals in their previous 18 Premier League games.
The Leicester player likely to damage Arsenal’s defence is James Maddison, who when fit this season has been scintillating this season, scoring 9 goals and 5 assists this season, only 2nd to De Bruyne for goal involvements from a midfielder and his importance shown by Leicester averaging 1.89 goals with him in the team, compared to 0.67 without him.
Coming up against a very vulnerable Leicester defence, Arsenal will turn to their man in-form in Bukayo Saka, who has been in great form this season, but especially since the World Cup, scoring 5 goals and providing 2 assists in 9 games and he will be confident against Leicester’s new 20 year old left back, Victor Kristiansen.
Arsenal’s 4-2 win over Leicester earlier this season at the Emirates made it 4 straight wins for the Gunners over the Foxes and it's not just at the Emirates that Arsenal are beating Leicester, in all competitions they have won 3 straight at the King Power, scoring 7 goals in the process.
