Liverpool were put through their paces in the intense heat of Tokyo on Tuesday ahead of a friendly with Yokohama F. Marinos, with Florian Wirtz standing out.The Reds will round off their time in Asia with a friendly against J1 League side Yokohama FM on Wednesday, kicking off at 11.30am BST.It will be their fourth warmup game of the summer so far and should bring an unofficial debut for their newest signing Hugo Ekitike.Ekitike was prominent throughout a busy training session at the JFA Dream Field in Tokyo on Tuesday, with 27 players working in the heat. The Frenchman, signed from Eintracht Frankfurt in a deal worth £79 million, could be seen working alongside fellow new arrival Wirtz in what resembled a two striker setup.While this could simply have been the natural dynamics of a No. 10 and a flexible No. 9, it could also indicate plans to incorporate two central strikers in Arne Slot‘s system next season.That comes with Liverpool preparing a bid for Newcastle striker Alexander Isak, who would undoubtedly command a key role if he were to make the move to Anfield as he wishes.Set-pieces took a big focus with first-team individual development coach Aaron Briggs – a vocal presence throughout the session – still helming those responsibilities.Briggs, who was viewed as a link between the academy and first team upon his appointment a year ago, took charge of set-pieces last season after the failure to appoint a specialist coach.While Liverpool may have plans to make such an appointment in the future – with interest in Feyenoord’s Etienne Reijnen – it appears as though Briggs will remain in charge as it stands.With academy goalkeeper Kornel Misciur between the sticks and a number of inflatable mannequins placed in the box, the likes of Ekitike, Ibrahima Konate, Virgil van Dijk and Milos Kerkez were seen working through a series of corner routines.Chief in taking those corners was Wirtz, who could become a regular standing over set-pieces following his £116 million move from Bayer Leverkusen.Liverpool lost one of their most prominent set-pieces takers this summer with Trent Alexander-Arnold‘s exit to Real Madrid and that could have an impact on the pecking order not only with corners but also free-kicks.To that end, it was interesting to see Van Dijk showcase an array of finishes from free-kicks towards the end of the session.Alisson was not part of the Liverpool squad training in Tokyo having departed Japan to attend to a personal matter, but Alexis Mac Allister, Darwin Nunez and Wataru Endo were all involved having missed Saturday’s friendly against AC Milan.Luis Diaz was also not present, with the Colombian now in Munich undergoing a medical ahead of his £65.6 million switch to Bayern Munich.Goalkeepers: Mamardashvili, Woodman, Pecsi, MisciurDefenders: Van Dijk, Konate, Kerkez, Robertson, Frimpong, Bradley, Tsimikas,Midfielders: Wirtz, Mac Allister, Gravenberch, Szoboszlai, Jones, Endo, Elliott, Morton, Stephenson, NyoniForwards: Salah, Ekitike, Gakpo, Nunez, Doak, Ngumoha
