Liverpool boss Jurgen Klopp is frustrated with the lack of time he has with his full squad before the Premier League kickoff.

The likes of Sadio Mane, Mohamed Salah and Roberto Firmino are yet to return to training and Klopp is worried about the effect of a packed summer schedule.

He said: “We sit here and it sounds like I am having a moan or whatever. It is just the situation, in the long-term, is not acceptable.

“For here (on pre-season) it is not a problem. We have all the boys here, apart from the three up front and Ali.

“It's not like after three days you can say to them, 'Hey! Come on! Let's start running again!'. They have had a tough summer programme. It's football.

“It's not riding a bike, so you lose a little bit (of rhythm). It will all come back but it will be a tough start.

“In the future, we have to change that. We have to change it. It is not possible (to continue)."
