Marcelo Bielsa gave his reaction to the achievement in his pre-Liverpool press conference on Thursday.
"I give a lot of value to the work that the current manager has and the group," Bielsa said.
"Especially taking into account that the under-23s is a constant help for the first team. This means their coach has to accommodate his plans depending on the needs of the first team.
"This weakens the programme of work that the under-23s can have. Within that scenario, that is not the ideal one. Their coach and players have contributed in a very, very valuable way."
