The way I see it we have 3 options for cover/medium-term replacement for Ferna:
1) Sign someone from another Premier League club.
2) Sign someone from another European club.
3) Promote from within.
If we start with option 1, I can see 4 players that could be under consideration. Each of them has pros and cons:
Ruben Neves (pros: young, good passer, Champions League experience, decent shot; cons - bit lightweight, used to playing in a 'double 6' with another defensive midfielder (can he do it by himself?), high transfer fee)
Declan Rice (pros: young, reads the game well, decent passer, physical presence; cons: lack of Champions League/big match experience; English premium - high transfer fee)
Idrissa Gueye (pros: breaks up play well, physical presence, experienced; cons: average passer, 30 this year - too old?)
N'golo Kante (pros: ticks all the boxes; cons: enormous transfer fee/wages needed to get him from Chelsea)
Option 2 (sign from Europe). Two names keep cropping up in this category:
Frenkie De Jong (pros: young, great passer/dribbler, done well in Champions League, schooled in possession football at Ajax; cons: initially too lightweight for Premier League (will take half a season to adjust/strengthen); transfer war with Barca, PSG etc - gonna cost a lot)
Tanguy Ndombele (pros: young, great physical presence, reads the game well, great on the counter; cons: a bit inconsistent; in demand - could be another bidding war)
Option 3 (promote from within). Who do we have already?
John Stones/Danilo (both better in their regular positions - we need a specialist)
Douglas Luiz (on loan at FC Girona - in and out of the side, is he kicking on as expected? Work permit issue again?)
Aleix Garcia (on loan at FC Girona - seems better suited to La Liga - found his level?)
Matt Smith (on loan at FC Twente - doing well, but it's the Dutch second tier; still only 19 - needs another loan at a higher level next season; potential to be a future squad player when Delph/Zinc move on)
Yangel Herrera (training with the 1st team after 2 seasons at NYCFC) pros: has a similar skillset to Ferna (see
https://www.fourfourtwo.com/us/feat...rld-cup-venezuela-nycfc-mls-manchester-city); did well in MLS; under-20 world cup Bronze ball winner; full international; cons: lack of experience in European leagues (needs a good loan to France/Spain/Holland this month).
Weighing up all the pros and cons, if I was Txiki I would draw up a transfer shortlist of Rice, De Jong and Ndombele, while keeping an open mind about promoting Herrera (subject to performance on loan).
