Manquillo was confirmed as Liverpool's seventh signing of the summer earlier in the week, and took part in the open training session at Anfield.
Manquillo joined the Reds on a two-year loan deal from Atletico Madrid, with Liverpool having an option to purchase the full-back at the end of that spell.

The Spaniard is expected to compete with Glen Johnson, Jon Flanagan and Martin Kelly for the right-back role in the side, with a couple of reports from the open training session suggesting Manquillo was operating on the right side of the defence, and Johnson on the left.
The 20-year-old will have been seen as a real coup for the Reds this summer given the calibre of clubs interested in him, including Premier League rivals Arsenal.
Brendan Rodgers will have wanted to resolve issues when it comes to defensive personnel this transfer window, and he has probably done that for years to come with Manquillo. He will be hoping that even though he has a lot to learn, he can provide the quality that can help Liverpool trim the amount of goals they conceded last season.
