The physical demands of the Premier League mean Joel Matip will be spending plenty of time in the gym ahead of the new campaign.
The new Liverpool centre-back, who has moved to Anfield from Schalke, conceded that he has a lot of work to do on his body to be ready for the start of the season.
"I am ready for it [English football] but I also have work to do on my body," he told the club's official website on the club's first day of pre-season training.
"This is another league, so I will have to work on my body to play here and to be physically strong [enough] for the Premier League.
"I decided to do it myself, but I think the coaching staff and manager will help me reach this level and to be fit for the season.
"Of course, the Bundesliga is at a high level. Maybe it's a different level, but it's also a high level and I think I have got enough to play here."
"There were many points: the coach, the club, the supporters… everything was good," he said.
"It was a good and simple decision for me. It's a great pleasure and honour to be a part of this big club."
