Barcelona's Champions League semi-final humbling against Liverpool looks to have been just the beginning of a long, long summer.
A year after they suffered an almost equally embarrassing turnaround against Roma, the Blaugrana are having to take stock of whether their current squad is still capable of being a dominant force in Europe.
Antoine Griezmann could well be the marquee signing they need after the Frenchman confirmed on Tuesday night that he'll be leaving Atletico Madrid.
Frenkie de Jong is already on his way and the La Liga champions are also favourites to sign Ajax team-mate Matthijs de Ligt.
If he keeps his job, Ernesto Valverde will also be tasked with clearing out any players he thinks aren't up to the standard required.

That leads us to Philippe Coutinho. Whistled, jeered, loathed by some corners of the Camp Nou - the Brazilian's dream move to Catalonia has quickly turned into a nightmare.
The playmaker left Liverpool in January 2018.
Yet in his first full season at Barca, the 26-year-old has only managed five league goals and two assists.
Coutinho could well be the most high-profile casualty of the result at Anfield and unfortunately for Liverpool, that could have ramifications for them too.
The Coutinho deal was broken down into an initial €120m (£104.1m) deal plus an additional €40m (£34.7m) in add-ons.
Mundo Deportivo report that Barca have only had to pay €15m in variables so far. That was for the midfielder playing 25 games and the second instalment came when the club qualified for the Champions League.
Now, here's the disappointment for Liverpool. If Coutinho moves this summer, the Reds will miss out on a further €20m (£17.35m) - the fee they would have got when he reached 100 games for his new club. The maximum he will have played by the end of this season is 77.
They will also forego the €5m (£4.33m) they would have been entitled to had he won a Champions League title at Barcelona.
So, on the pitch, Jurgen Klopp's side have fared just fine without their old talisman, but his shortcomings could prove a significant blow off it.
At the very least, the board can console themselves with the £13m in prize money they've earned already by reaching the final - and there's another £3.47m lying in wait if they beat Tottenham.
