Jurgen Klopp will have been delighted to have had a full session with the bulk of his first-team squad after a number of key players returned to training as preparations continued for the clash with Premier League leaders Leicester City on Sunday.
The likes of Georginio Wijnaldum, Roberto Firmino, Alisson Becker, Takumi Minamino, Xherdan Shaqiri and Kostas Tsimikas ensured the set of returning international stars was completed on Friday evening.
Wijnaldum returns off the back of captaining Holland to two crucial victories in the Nations League over the past few days.
The 30-year-old was named stand-in skipper in the absence of Virgil van Dijk and he rewarded manager Frank de Boer by scoring twice during a 3-1 over Bosnia and Herzegovina on Sunday.
