I think the way we brought in Jota tells me the club are taking steps to address things. If Eliott shows up to be something special, and Konate too, I think it's clear the rebuild is already happening.
I expect we will sign a winger and a midfielder with world class potential next summer
Yep this. There is no urgency, the sky is not falling, as some of our more 'emotional' posters would have you believe. This group are good, with blooding new players at an average of two per year, for the next 4-5 years.
Basically looking at the squad we have at least 7, maybe 8, positions covered for the next generation of this team (28, 24, 22, 27, 22, 27, 18, 20, 24, 17) noting that older players can easily play into their mid-30s in some positions (GK & CB and maybe DM for example), and these are already covered with the new contracts, and barring something unforeseen, for the next 5 years. Squad depth within that 5 years is another issue.
I'm assuming that Milner, Ox. Origi, Minamino and Nat will all be gone within the next 12-18 months.
Ali (28) + Kelleher (22) = good for the next 5 years at the very least.
VvD (30) + Matip (30) + Gomez (24) + Konate (22) = good for the next 5 years at the very least.
Robbo (27) + Tsimitas (25) = good for the next 3-4 years.
TAA (22) = clearly we need backup here as Neco W. isn't going to be around for much longer. Likely one of the key positions to address, especially if Trent moves into midfield at some time.
Fabs (27) + Hendo (31) linked here because Hendo is the de facto replacement when Fabs is missing for any reason = Fabs is good for the next 5 years though a replacement for Hendo will be required sooner rather than later (blooding within 2 years, take over in 3).
Thiago (30) + Keita (26) + Elliott (18) + Jones (20) = considering mobility required I'd give Thiago 2-3 seasons tops. So another couple of high quality midfielders are required over the next two seasons.
Firmino (soon to be 30) + Jota (24) + Salah (29) + Mane (29) = Good for the next two seasons but we'll need to address both Salah and Mane in the next 24 months (as in blooding replacements even if they don't relegate them to the bench for another season after that). I'm guessing Bobby will be gone within 2 years but it could be longer if he's happy to accept a bit part. Clearly Gordon is likely to be one of them.
By my reckoning that's maybe 6-7 new players over the next 3-4 years. That isn't an emergency and shows the value of tying down our existing stars with new contracts.
