Didn't say he declined. Read again.
Didn't play his best football under Pep. One of the many examples how Pep's not necessary or a guarantee to facilitate player reaching their ceiling
Utter nonsense. Lovren was terrible under Klopp, a constant liability that had to get subbed out in crunch games at 30 min mark (i.e. memorable 1-4 to Spurs) and club was desperate for Matip to be fit all the time
Lovren's best individual level was at Southampton under Pochettino. Way out his depth in Klopp system
Could talk about other players from that team just as well
Moreno played best football of his career under Emery right now before reinjuring
Kabak was a meme under Klopp despite being Bundesliga rookie of the season year prior
Plenty examples
Yup was fine and doesnt support the claim he was best of his career under Pep because he wasnt (in fact was better even in first season after he left) and null point to hypothesise he'd be better under somebody else as can't test and yet presenting it as fact.
And played the best individual football of his career well after leaving both of them behind
As above, played best football of his career after leaving Pep behind. Wasnt under him he was best
Yup as above, got hurt, got worse and got shipped out
Aye, played rubbish and Pep did nothing to his career despite asking for him and even wanting to keep him at the end
Didnt play best of his career under Pep either
As above, not supporting thesis that players are guaranteed to play best football of their career under Pep
Great coaches are not a guarantee of facilitating player improvement even if you'd like to present it as such as fits your POV
If Yaya was needed and had stayed another 4 years at Barca under Pep, he would have played his best football there and not at City.
Kabak was an emergency solution thrown suddenly into deep waters, why is he even in the discussion?
You are confusing several things here.
A) if X player factually happens to play his 'best football' elsewhere, under another coach other than Jurgen and Pep, that doesn't mean that Pep or Jurgen didn't activate the potential and another coach achieved that (Which was my argument to begin with)
Many reasons can contribute to that, like for instance staying only 1 fucking year under Pep or Jurgen. Hence all those examples you are trying badly to make them sound as counter-examples like Mandjukic or Kroos are irrelevant, as we don't have the duration (sample size) necessary to judge and the short period they stayed under Jurgen and Pep were fine or more than fine
B) If X player is certified B-tier and his ceiling is B-tier no matter who the coach is like Chugrynsky or like Lovren - considering the tier Pool tried to hit with Jurgen -
that's not on the coach.
Lovren might be alright for Zenit, but will never be alright for Liverpool because the lowest necessary for Liverpool is above the highest possible for Lovren.
Simple as that, and Klopp squeezed out the best he could from this limited defenders.
Same for and all the other ridiculous B-tierers Jammy dropped, like Nolito Danilo Otamendi, LOL
C) the argument was about Mbape and whether his ceiling can be achieved.
So, a top WC prospect at the best age, which is going to play many years for a big club and fight for biggest trophies.
And my argument always was that such WC young talent is guaranteed his ceiling (as far as the manager is concerned. If the player for instance has psychological problems he would never attain his ceiling under any manager whatsover)
with someone like Klopp or Pep, and that's dubious under other managers.
To refute that you have to find a counter-example of a similar WC prospect that flopped under them,
not a B-tier utility player who looked better in the B-tier where he always belonged, not someone done looking to get into a retirement league, not someone who couldn't play any more after breaking his legs.
