If you’ve downloaded the previous patch (11.1.0) & (11.1.1) we still highly recommend that you download the new patch (11.2.0) to experience the most up-to-date and best Football Manager 2011 experience.
If you haven’t downloaded the previous patch (11.1.1) please be aware that by downloading the new patch (11.2.0) you will automatically get all of the previous changes / fixes from previous patches, so there is no need to download 11.1.0 and 11.1.1 – just download the latest version 11.1.1.
