Probably the weakest depth part of pour team is cb Zat, and the strongest is cm, so your option is to play holgate in back 3 and drop out a centre mid effectively?
Removing Bolasie and Coleman as theyre crocked. Assuming we sign Sigurdsson;
Pickford/???
Kenny/Martina -- Keane/Holgate -- Williams/Jagielka -- Baines/???
Klaassen/Davies -- Schneiderlin/??? -- Gana/???
Rooney/Mirallas -- Sandro/DCL -- Sigurdsson/Lookman
Does this side look like it could challenge the top 4 to you (even if you include those ive omitted)?
Clearly we need a centre back, left back and a centre midfielder in there to rotate.
But the centre forward and right attacking slots are so weak compared to the left side if we signed Sigurdsson.
Even after Sigurdsson we would need 4 players and if we switched to a back 3 we wouldn't have the players.
Key for me is centre back and left back. We cant go into a season with these centre backs nor with one left back.
If we go with a 2 or a 3 were still in trouble defensively.
Stekelenburg, Martina lol , Williams, Jagielka are not names I'm eager to see protecting our goal.
Even though were only in mid July still I am a bit concerned that were linked strongly to Sigurdsson for such a huge amount and also giroud but aren't actually in talks for top defenders.
I expected Koeman to work with Walsh and bring in some class defenders with Keane...not Cuco
