For Liverpool supporters, much of the focus on the opening of the summer transfer window was on big names, with incomings and potential outgoings indicating another major reshuffle of the first-team squad—prompted by manager Jurgen Klopp, overseeing his first pre-season in the dugout on Merseyside.
Serbian midfielder Marko Grujic received his work permit to take up his role in Klopp's new-look squad at the beginning of July, as reported by the club's official website, while a pair of imports from the Bundesliga arrived at Liverpool's Melwood training facility in goalkeeper Loris Karius and defender Joel Matip.
