This isnt about transfer planning. But, Tchouameni wasnt signed to replace Modric. You can make a case for Bellingham but Salah isnt 38 either. We dont know yet how we have planned to move on from Salah given he just turned 31.
The point is that most people shouldnt be allergic to keep some players into their 30s. Kroos also signed a new contract, btw.
How was Tchouameni not signed to replace Modric? Of course he was.
It's just that Real sees succession planning over a longer time period than we do. They identified a need to have replacements for Modric and Kroos at least 2 and maybe 3 seasons before actually necessary.
We wait until the wheels fall off, give it at least one more transfer window after that, and then head at it. Or at least we have with midfield and defence.
I'll give us better grades for finding the next Mane and Bobby but, despite the likelihood of Mo continuing to do well for a few more seasons, we had better be looking at right attackers if for no other reason than to help prolong Mo's time at the top.
