Ferna wasn’t a defensive midfielder when we signed him. He was an outstanding box to box player with brilliant all round attributes - passing, shooting, tackling, mobility, aerial ability - and also the football intelligence, character and discipline to be moulded into playing the holding role.
So might Pep be looking at a similar profile of player to replace him rather than a current DM specialist?
If so, then one who stands out as having similar attributes to Ferna when we signed him would be Tielemans at Leicester. Likes a tackle, good energy and very good quality on the ball. He would be expensive but a miles better fit for us imo than a technically limited destroyer like Ndidi
