(Reuters) - Arsenal must focus on keeping Alexis Sanchez and Mesut Ozil at the club before trying to strengthen other areas of the team for next season, goalkeeper Peter Cech has said.

Arsenal's leading goalscorer Sanchez and playmaker Ozil are out of contract in 2018 and talks on an extension have been put on hold until the end of the season.
