Can you clarify this statement? Lallana and Coutinho are our two most talented players (along with Sturridge but he's not putting that talent into performances so it's kinda irrelevant) and have just signed long-term deals. They both start every important game they're fit for. He also clearly loves Firmino. Three attacking players right there he's hugely trusted from day one, to the point that he's sacrificed playing an out-and-out nine many times in order to get them playing together as a front three (or now four with Mané).
Then you've got Clyne who is Mr Reliable and Henderson who he has favoured over Can as an "international class number six" this season. His words not mine.
With those two you mention plus those five I mention that's seven players I think he definitely 'trusts'.
It's perhaps too early to put Lovren and Matip as a partnership within that bracket but I personally think they have done well together this season. He will almost certainly trust one of the two as a first choice centre back next season.
Wijnaldum is a weird one because although he clearly likes him, he has chosen Can ahead of him plenty of times too, so I think that is a position still up for grabs despite Gini's big game excellence.
You can't say he trusts either goalkeeper because he's flip-flopped between the two. But equally, he appears to view Karius as his long-term number one, and Mignolet received a five-year contract not all that long ago. It may well have been to preserve his value, but it could also have been a show of faith to remain in the squad for the long haul. I don't think it's a certainty in the slightest that we buy a goalkeeper this summer.
So overall I think a) you do down how many of our players Klopp trusts and rates as a first-team player and therefore b) I only see a maximum of four or five first-team spots up for grabs this summer, and within that I only see one near-certainty (a top-class centre back with a top-class injury record). Goalkeeper, left back, central midfielder, winger, striker - I'd be amazed if we were to get all of them.
I meant trusts to bring into those positions without moving everyone else around (he blatantly has about 13 players he currently trusts to play, but we need more).
For leftback, who would everyone play in a crunch match against say Man City away? Would you trust the current reserve left back, Moreno, or try and move Clyne to left back and bring in Trent at right back? My point was, if someone is missing we absolutely should not be moving a few of our best players round the team to accommodate this- we would need a back up good quality left back Klopp absolutely trusts to fill the role. For Mane, when he was out we ended up moving one of our most effective players this year, Lallana, out of position due to a lack of suitable replacements. Same with Coutinho being injured and us moving Firmino out of position and resulting in him, and the team, being less effective.
We need a good back up left back, plus I would argue a wide player (who can play left or right) and a forward who can play wide or lead the line. Plus we need a cb, another cm and, if available, a brilliant top level goalkeeper (I'd rather not waste money on a marginal improvement here). Its arguably too much to do in one summer and bring in sufficient quality.
In terms of out field players, we'd then have;
Defence: Clyne and TAA as RB. Matip, Lovren, new signing, with Klaven and Gomez as cover for CB. Milner and new signing for LB
Midfield: Henderson, Lallana, Wijnaldum, Can, new signing with Grujic, Coutinho and Milner who can cover
Forwards: Mane, Firmino, Coutinho, Origi, new winger, new forward with cover from Ings, Woodburn and Milner
That looks much healthier and balanced, with numbers better balanced across the squad and hopefully better options for rotating due to injuries, form and fixture congestion (you'd hope for 18 outfield players trusted with other decent options as cover from this squad list). The three biggest signings for me would be both forwards and the midfielder (because I like lots of good options who can win games!).
