Andoni Iraola named a youthful squad for the tour of the USA in July - with a host of key names still away on their post 2026 FIFA World Cup breaks - including captain Virgil van Dijk.
The Reds signed off on their summer campaign with two Anfield clashes against Como - one ending 0-0 and the other in a 2-0 win for Iraola.
Van Dijk started the latter game, alongside new arrival Jeremy Jacquet, on his first appearance since joining from Rennes last month.
Liverpool agreed a deal for the Frenchman back in January, but he was permitted to stay in France for the final months of 2025/26, and subsequently suffered a shoulder injury which needed surgery.
Jacquet has been eased into action by Iraola and he scored on memorable debut - before being replaced by fellow debutant in Ronald Araujo at half-time - as the Uruguay international made his Liverpool bow after joining on loan from Barcelona.
Van Dijk remains first choice at the heart of Liverpool's defence and he hinted Jacquet is a little ahead of Araujo - but insisted both players need time to settle.
"I think Jeremy did well, same as Ronald. It's a good start so hopefully he can crack on.
"We build a relationship by playing games. It's not the only way, but games are totally different to training.
"Jeremy's English is, I would say, a bit better than Ronald's, but we're all pretty good footballers. We can see and smell moments on how to defend certain situations.
"It's pretty clear you need to form a connection together and that takes time."
