Lijnders told Liverpool's official website: “We had a big focus on our set-pieces this morning. In these training camps, it's about not only about going back to basics, but also about putting in new ideas and make steps to evolve and become better.
"I also have to highlight that Ox has scored some absolute worldies in training in these last few days – and you absolutely love to see it!
"The other evening, when the staff came together after the day's training – the coaching staff, the physios, the press team – we had the idea to play a game.
"We never normally do that because we're always usually watching football games, but we had this idea to play Uno because one of the kitchen staff had brought it with her."
"We played it with a lot of people and one thing is for sure, you immediately learn the characters of each single person."
