Liverpool have made a strong start to the summer transfer window and are now working on a big-money deal to sign Florian Wirtz from Bayer Leverkusen.

Florian Wirtz has one clear shirt number alternative should he complete a summer transfer to Liverpool. The Germany international is subject of interest from the Premier League champions, though they have seen two bids rejected by Bayer Leverkusen - including a club-record £109m offer.

Mark Flekken has come through the door from Brentford in a move that had a direct impact on Caoimhin Kelleher's future, as he joined the Bees as his replacement in an £18m deal, but a fee upwards of £100m will be vital for Die Werkself to regroup and challenge Bayern once more.
