But there's no doubt a pivotal summer awaits for Liverpool and sporting director Richard Hughes in particular.

Those who place as much emphasis on winning the transfer window as actual silverware will perhaps be rolling their eyes at this juncture, claiming to have heard it all before.
Not least last year when, despite the arrival of Slot suggesting a fresh start, Federico Chiesa - who has only made three starts all season - was the sole new addition for this campaign, with goalkeeper Giorgi Mamardashvili to come from Valencia in the close season.
But necessity as much as design dictates it will be a busy forthcoming market for Liverpool with Slot having had a full campaign to assess where his squad needs tweaking and upgrading.
And there was a telling remark from the Reds boss when quizzed after Tuesday's game over whether PSG could now go on to be anointed European champions for the first time.
He created in a few transfer windows a team I assume he is quite happy with, not only in terms of team performance but individual."
For all the talk of PSG having stepped away from the 'galactiques' era of Neymar and Lionel Messi, they have still spent big in recent years.
In the four transfer windows that have taken place since Enrique was appointed boss, the French side have had a net spend of a whopping £300m.
But there will undoubtedly have to be a loosening of the purse strings from Fenway Sports Group with Slot having shown this season with a group of players he inherited from Jurgen Klopp the Reds can challenge strongly for major honours.
Of course, there is already money there, as evidenced by the failed attempt to sign midfielder Martin Zubimendi for £51million from Real Sociedad.
But it's likely the outlay will have to be several times that to plug the potential holes and ensure the necessary improvements in the squad.
The summer, then, will be the first real test of Hughes and the retuned recruitment team having still been adjusting to their new positions last year.
For all their pace and power in attack, the French side scored only once in 210 minutes against the Reds, and even that was a scruffy effort that owed much to a brief breakdown in communication in the Liverpool rearguard.
With Slot having already indicated the Reds are in the market for a forward, the dearth of top-quality strikers means they will face strong competition with Liverpool among the many admirers of Newcastle United's Alexander Isak.
