As the dust settles over Liverpool's historic comeback win at Anfield against FC Barcelona on Tuesday evening, Barca manager Ernesto Valverde has been subject to high levels of criticism as his team failed to even switch to the top gear against Liverpool, let alone giving them a tough fight.
In the post match press conference, Valverde accepted the responsibility for the defeat hinting that he was not fully prepared for such a response by Liverpool in the second leg.
Barca were favourites for the semi-final even before the first leg, and their 3-0 masterpiece at the Camp Nou almost had the whole world thinking that they have made it to the final of the competition. But Liverpool had other plans.
The Reds brought their 'A' game to the second leg, and won 4-0 to make it 4-3 on aggregate and proceeded to the final of the competition, after two goals each from Georgino Wijnaldum and Divock Origi, with the latter being named the Man of the Match.
Lionel Messi, who had vowed to bring the Champions League trophy back to the Camp Nou in his speech during La Liga title celebrations last week, had a night to forget on Merseyside as he missed a very clear chance to score as Virgil van Dijk dispossessed him at the last moment.
As Barcelona fans still get over the result and their team's big failure, one thing's for sure - majority of them do not want to see Valverde at the Camp Nou next season, and that brings up a great discussion as to who can bring back the Champions League glory days back at Barca.
Today, we take a look at the top three managers who could replace Valverde, and considering their potential, can actually take Barca to European glory next season.
#3 Laurent Blanc
The ex-Paris Saint-Germain manager has been out of football managerial duties for the last two years since he was relieved off his duties by the French club.
Known as Le President due to his excellent leadership skills during his playing stint with Marseille, the Frenchman is one of the best tactical minds in world football. His record with PSG suggests the same.
During his three-year tenure at Paris Saint-Germain, he won the domestic league in each of the three seasons, in addition to two French League Cups, three French Super Cups and three French League Cup trophies.
Blanc was sacked by PSG after the club's failure to make it to the relevant stages of the Champions League, but at Barcelona, the French coach could actually realize his goal again, and could actually win it considering the firepower in the Barca squad.
Blanc would be a great choice if the club want some fresh tactics in the near future.
#2 Giovanni van Bronckhorst
Any football fan would remember Giovanni van Bronckhorst for his screamer in the World Cup semi-final against Uruguay in 2010.
But the former Arsenal, Barcelona and Netherlands player has also been making his mark in the football managerial world recently.
After having worked with Ronald Koeman as his assistant manager at Feyenoord, Van Bronckhorst took charge of the Dutch club in his own hands, as he was unveiled as the first-team manager in 2015.
He guided Feyenoord to an amazingly shocking league title in 2016-17 after toppling rivals Ajax for the same.
Van Bronckhorst has announced that he would be leaving Feyenoord at the end of this season, and that means he would be available for Barca to hire him next season easily. Barcelona have had a great run with Dutch coaches in the past, with Johan Cruyff and Frank Rijkaard being managerial legends for the Catalan giants.
#1 Erik Ten Hag
If Erik Ten Hag could reach the Champions League semi-final with a young and inexperienced Ajax squad, just imagine the wonders he could do with an established squad at Barcelona.
Even if Ajax failed to make it to the final of the competition, having beaten by Spurs last night, the whole footballing world has been in awe of them for the past month after their amazing results against Real Madrid and Juventus.
Ten Hag's style of play is extremely attractive and very similar to Barcelona - a direct style of attacking football, with involves moving the ball forward very quickly.
With his Ajax protege, Frenkie de Jong having joined Barcelona in a £75 million deal, and club captain Matthijs de Ligt also linked with the Spanish giants, it would be another bait for the Dutch manager to join the club.
Maybe, just maybe, next season he could actually win the Champions League with De Jong and De Ligt in his squad in Barcelona colours.
