Barcelona boss Luis Enrique has revealed that he is sometimes left stunned by his team during training sessions.
The Spanish champions have been widely praised for their second-half performance against Celta Vigo on Sunday night, which saw them score five times to record a 6-1 win in what threatened to be a tough fixture in the first period.
When Enrique was asked about his team's display, the Spaniard claimed that his players perform "even better" during training.
"I see these players be even better in training and some things make you stand still," Enrique told AS.
Barcelona are currently on a 30-game unbeaten run in all competitions, which stretches back to the start of October.
