Down 3-0 after the first leg at the Camp Nou, Liverpool did the unthinkable at Anfield, turning around the tie with four answered goals in one of the greatest comebacks the Champions League has ever seen. However, despite that and his celebration last week, most Liverpool fans seem to still hold the striker in high regard.
Appearing as a pundit on BT Sport, Fowler said: "Before the game, we were talking about all the superlatives we can about Messi".
"We tried to build on the performance in Barcelona and all the good things we did there and try to win the game step by step".
Trent Alexander-Arnold (Liverpool): Two goals apiece for Wijnaldum and Origi, but Alexander-Arnold gets the nod for his moment of brilliance in the build-up to the fourth goal.
The forward who also grabbed a key victor at the weekend in the Premier League against Newcastle also got the decisive goal that saw Barcelona knocked out, 11 minutes from the end.

Just when Liverpool fans thought they had seen it all - the so-called "Miracle of Istanbul" in particular, but also those storied comebacks against Saint-Etienne, Olympiakos and Borussia Dortmund down the years - along came another European competition night that just might beat them all.
'The emotions that this place evokes on nights like these, there hasn't been a better night than this.
They took that to heart.
Origi's timing in scoring his first Champions League goals was impeccable, as was Wijnaldum's introduction for injured defender Andy Robertson for the second half.
'What they've produced here is breathtaking and you can do nothing but respect the team, the management, and the way this club have conducted themselves, especially on a night like tonight'.
Former Liverpool winger Luis Garcia joined the chorus of approval for his old team's heroics.
"And Robbo [Andrew Robertson] got the heel I think of [Luis] Suarez against his calf, so you saw both limping".
But there was a sense of hope around Anfield that there might be another historic Champions League evening under the lights.
