Jose Mourinho has taken another fresh swipe at former club Manchester United - this time about their ballboys.
Liverpool used their ballboys to full effect on Tuesday night as a quick Trent Alexander-Arnold corner set up Divock Origi for the winner against Barcelona .
Sunday Mirror Sport reported in January 2017 that Mourinho had axed United's ballboys because they were not up to standard.
The Portuguese drafted in players from United’s Under-16 team, after the previous ballboys and girls were provided by the Manchester United Foundation.
And Mourinho has again hailed Liverpool's secret weapon and believes it showed just how important they can be.

"You want a quick throw in, the ball boys need to know you want a quick throw in. The ball must arrive fast. I had a club where the club never understood how important the ball boys are," he told RT.
Even if you are winning, that speed is important. The goal kicks, the tempo of the game, the ball boys, in a good structure, can also play a part
"People don’t know that a real football club, every detail is very, very important. In this game, the kid, very intelligent, very bright. I don’t know if he’s an academy player or not, but the kid knew what he was going to do."
What Jurgen Klopp told Steven Gerrard during 90-minute meeting
Fourteen-year-old Oakley Cannonier was the ballboy whose quick-thinking saw Liverpool go ahead.
Mourinho went on to single Alexander-Arnold out for praise after Liverpool reached the Champions League final.
"Then Alexander-Arnold, he read the situation fantastically well. Young kid, Champions League semi-final, tired, 80 minutes of football," he added.
"He saw everything. I always say, the good players are the ones that are on the pitch and everything is clear, they see everything. He saw that."
