I think wecan play 3 at the back. I think it's why we signed N'Doye. We've played it with a poorer squad, now we have a popper back to goal number ten I think we can play it. It's ok saying we haven't got the defence to play 3 at the back, but we haven't been able to play 4 at the back because everything that goes out comes straight back, the pressure on the defence every game regardless of the system has been too much, we've got the worst defence in the league playing 4 at the back for 90% of the season. Now with N'Doye and Khazri we've got players further up the pitch to retain the ball. The pressure should drop off the defence considerably now, opening up a multitude of option and systems. Now we can defend from the front and attack from the back. Sam is bringing in good balance and options. Don't see how limiting ourselves to one predictable system can ever complement the work put in this window. We've got options now, we should use them imo.
