This would be what we used for the cl wit baros up front, riise and garcia on the wings, stevie and didi in the middle and mori and baros up front. It's what we've been using most lately and we looked very good in attack on tuesday.

This would involve playing didi as the holding midfielder and stevie and igor attacking. Riise on the left wit mori up front and either garcia or baros on the right linking up with mori. It workrd against chelsea on new years, and arsenal.
Obviously our backline would be the same either way.
