Yes I agree.
2 of those players fit into the young, hungry players with really good domestic experience. I have my doubts about Keane-Lewis Potter on price, as I don't think we will go to 30m. He has 2 years left on a (well 1 with a club option 1) so it may be we sort of tap him up this summer for a deal next year which will be cheaper. One was to smooth it, may be to offer them Dobbin on loan, as a close like for like replacement.
Our major issue though, is buying young players for the future is great, but there's also the contradiction for the here and now. If we are losing experienced players (and I still think DCL/Richarlison may go) we have the massive concern of relegation. This season has shown, with a few things coming together, it can be a very real prospect. You lose a lot of experience, a few injuries kick in etc it will always be a danger for us. That's partially what I see a signing like Tarkowski to be. An insurance policy, for a young manager, young squad in a league where 3 teams go down. He knows the league, plays most of the games and is very good off set pieces. Essentially ticks the boxes that need ticking. It's not even a big initial outlay on fee. We have to pay him more than we might want wages, but you look at the wages going off, and it gives us a bit of wriggle room. Plus these younger players will not be on mega money initially.
It sounds a bit dramatic, but it's a bit like Reid/Gray in the 80's with a young squad. Just gave it the missing ingredient.
What is also good is that we have a niche. Probably our biggest competitor would have been Gerrard, same sort of pull, at a big club, with money to spend. He seems to be going for more experienced players, which seems to negate his pull, but frankly work in our favour. I know there's Viera at Palace, but we are a bigger club, and think Lampard is probably more known for playing younger players. We can also pay more money (though we have to be careful about that in future).
You look at the work Lampard has done, improvements to Iwobi, Mykolenko, Gordon, (to a degree) Holgate. The introduction of Welch and Price. Getting Richarlison back on track. The answer is clearly to keep feeding him younger players to work with. But you do need a couple of decent senior pro's to help that process. It's no coincidence, we looked better when we got Delph, Allan, Mina etc on the pitch. You need to have that balance in certain games.
