You know Mourinho, he'll switch it up depending on the matches. 2 DMs for sure against stronger sides, or a 3 man midfield with Cesc-Matic-Ramires with 3 up front. At home he might play more attacking against stronger sides but away he'll definitely be more defensive, but I think Cesc will always be there. Against the weaker and some mid-table sides I see him playing Cesc-Matic with 3 AMs and Costa up front.
