Arsenal manager Mikel Arteta has indicated a willingness to change up his line ups.
The Gunners boss has come in for some criticism regarding the rigidity of his team sheets.
However, such selections do breed consistency, which has propelled Arsenal to the Premier League summit.
Asked about selection headaches in his pre-match press conference, he said: That's more determined by results, but for us, it's more about performances and what players have given us to take us to the position we are in today.
They deserve opportunities. Obviously we are looking to give players opportunities that they deserve. You talked about Leo - we're talking about anybody who has had minutes in this league. There will be changes - it will happen and very soon.
Every team is trying to work out what we do, the same that we do with every opponent [we face]. When I look at the games and what we produce, I'm usually very satisfied with what happens.
Sometimes we can do better because there are many factors that can determine that, but we are always looking to evolve to be better with the players we have, and put them in the best positions to win the games."
