The Reds were greeted by rain—and several hundred fans at the team hotel—when they arrived in Qatar on Sunday, fresh from the 2-0 win over Watford the day before.
Wijnaldum’s inclusion came as a surprise given his withdrawal due to a hamstring injury at Anfield, and the Dutchman ultimately sat out of the first training session.
He was joined on the absentees list by Van Dijk, though there is no indication at this stage whether this was due to an injury or simply a lengthier recovery after Saturday’s victory.
Teenager Neco Williams was involved after being drafted into the initial squad along with Curtis Jones, despite previously being expected to play in the League Cup quarter-final at Aston Villa on Tuesday night.
Mohamed Salah was the main focus for the cameras at Qatar University, with the Egyptian having scored three excellent goals with his weaker right foot last week—one at Salzburg, before a brace to down Watford.
He is likely to start against Monterrey in midweek, though Klopp could opt to rotate once again, as he navigates a busy winter schedule.
Shaqiri has already won the Club World Cup during his time at Bayern Munich, and speaking to the club’s official website the Swiss described it as “an amazing experience.”
“We will do everything to win. It’s going to be good—good weather, good teams so we have to enjoy it but also try to win it,” he continued.
“It’s an opportunity to win it and to bring one more trophy back to Liverpool.”

The manager will be hoping he can avoid too much experimentation, however, as he sets his sights on more silverware following the UEFA Super Cup win in August.
