Liverpool must spend big this summer if they want to keep up with Manchester City, says Anfield legend Ray Clemence.

The Reds finished just one point behind City last season in a thrilling end to the title race.

But Jurgen Klopp has been slow to make waves in the transfer market. Only unknown 17-year-old defender Sepp van den Berg has been drafted in from Dutch outfit PEC Zwolle, in a deal understood to be worth an initial £1.3million.

Champions City are yet to make any acquisitions at all in this window, but Clemence, who won five league titles and three European Cups during his time on Merseyside, has warned that their boss Pep Guardiola won’t be resting on his laurels.
