the 3 of them could take it in turns to do the sitting, i think bissouma can offer us some quality by being allowed to go forward too. he looks a good player, clean touches and looks confident on the ball.Agree , with Bissouma sitting , they can then get forward which certainly helps
bentancur looked like he done well to stay on his feet after some of the sprints earlier. he looked absolutely spent. thats when he should be doing the sitting to catch a rest and let bissouma do the yards. think all 3 have the intelligence to play the holding role.
