Which roles did you use for TAA and Endo, and how did you balance it with your LB? I did the same with Endo. TAA is my clear #1 with Gomez/Endo/Bajcetic all being able to play there as backup/rotation. Mostly had TAA as a IWB(s) and Endo/Baj/Gomez as IFB(d). Since all of my LBs (Tsimi, Robbo, Barco) are offensive, towards the tail end of the season I tried TAA as an IFB(d) with 'take more risks', 'cross more often' and 'cross from deep' which actually seemed to be quite decent as well.
Not sure how I'm going to play them for next season though, so looking for suggestions. Mostly played a 4-2-3-1 with 2 dms, but also tried moving the holding midfielders up to cm and have a 4-3-3 as my third tactic. All of them is more or less the vertical tiki-taka tactics with minimal changes.
