Big job in the summer to identify the right players to come in, work hard and suit koemans style of play.
Think we will mostly be aiming for players in the 23-28 category and bring the average age of the squad down a bit as we phase out the likes of barry, jagielka and even to an extent baines (still a few years left in his case)
For me the midfield is sound, we have a great set of young hungry players there with qualify through out. The only thing we lack is a Silva, mata type player which I'm sure will be a target.
For me the main positions in the summer to bring in for a champions league challenge would be :
Goalkeeper, Joel needs a run to see if he can be our keeper. He has improved massively IMO and could well save us the money, if he continues his performances this would not be a priority for me, instead we should identify a young goalkeeper for loedwijks go improve and sit on the bench / play for the under 23's.
Center half - we need quality in there, maybe height too. Be it Keane, manolas, or soneobd left field that we've kept an eye on, someone who can play in a 3 or in a 2 comfortably. This has to be a priority for me. And done as quickly as possible when the season ends.
Striker - we have plenty of "second strikers" players who play off the target man and buzz around them, lookman, Barkley, mirallas, bolasie can all do that job, what we lack is someone who can hold the ball up, be strong in the air and hold the ball up to bring others into play. I'd honestly love us to get Rondon, but if not someone of his mould.
Left back - we need a quality long term replacement for baines, which is going go be one of the hardest bits of business we can do. Ideally we could get someone like Ricardo Rodriguez, unlikely though so I'd make a early move for cresswell.
Other than that some youth players to develop and maybe a winger and we'd be set .
