Reigning league champion, currently top of La Liga and through to the next round of the Champions League – so why did Barcelona sack its coach Ernesto Valverde?

For most clubs, winning successive league titles, progressing to the knockout stages of this season’s Champions League as group winner and being captained by Lionel Messi, one of soccer’s greatest players, would be reasons to triumphantly cheer.

But Barcelona is different, it views success through a different prism, which is why Valverde’s reign has come to an end after just under three years at the helm.

Another former Barcelona player linked with the job was current Netherlands manager Ronald Koeman, but with the Dutch among the favorites to win this summer’s European Championship it always seemed unlikely that the former Barca defender would return to the club this season.

Valverde oversaw training on Monday, but it always felt he was on borrowed time and so it turned out to be with the club announcing his sacking la
