Liverpool F.C. have the option to seal a £55m transfer with terms already agreed. The deal is related to a buy-back clause written into the sale of Jarell Quansah to Bayer Leverkusen for £35m last summer. The buy-back clause is a key factor in the transfer negotiations. Liverpool F.C. officials have not stressed the sudden need for a replacement this summer. The club may look more intently at the centre-back market during the window. Giovanni Leoni and Jeremy Jacquet have been talked up privately. Jacquet is yet to officially arrive at the club, but his £60m switch from Rennes is set to be confirmed on July 1. Liverpool F.C. fended off competition from Chelsea to land the 20-year-old. Jacquet spoke last month about his desire to learn by watching and training closely with Konate and captain Virgil van Dijk. At least he will have the opportunity to pick up plenty from the Reds skipper this pre-season. Of course, expecting a player who only turns 21 next month to immediately shine at the sharp end of the Premier League is a big ask, particularly at a time when Liverpool have a lot of issues at right-back. Jeremie Frimpong has yet to convince in the role and Conor Bradley is still finding his way back after a long-term knee injury ended his campaign in January. Even with a partner as vaunted and as experienced as Van Dijk, it is unfair to expect Jacquet to calm the disquiet over the nature of Konate's departure and his new team-mate, Leoni, has his own troubles to contend with. The Italian looked a seamless fit during his one and only Liverpool appearance, but an 80-minute cameo against Championship side Southampton in the League Cup is no real barometer to measure Leoni's current level, despite the understandable excitement at his potential. Liverpool may, to borrow a Richard Hughes phrase, be taking an 'opportunistic' approach to centre-back signings this summer but their failure to land Marc Guehi last year looks worse than ever, even if the enormous wage packet offered by Manchester City made steering clear of a January pursuit seem more reasonable. Even with the question marks around Jacquet's ability to immediately fulfil his potential on Merseyside - particularly since he is coming fresh off shoulder surgery earlier this year - and the obvious issues around Leoni's season-ending ACL injury, the Reds believe they have signed two of the best young defenders in France.
