The Germany winger is one of the best young talents for Europe and has been targeted in the past by Barcelona, Bayern Munich, Liverpool and Real Madrid.
Chelsea, who were under a transfer embargo last year, are giving Lampard strong backing as they look to close the gap on Liverpool and Manchester City at the top of the Premier League. They are close to strengthening at left-back by buying Leicester’s Ben Chilwell for £50m, have offered Silva a deal and are poised to sign Havertz after negotiations with Leverkusen over a fee for the 21-year-old.
Havertz, who has agreed terms with Chelsea on a five-year deal, had made it clear he wanted to leave Leverkusen this summer following their failure to qualify for the Champions League. Chelsea had an initial offer of €65m (£58.6m) plus €15m in add-ons rejected last week but negotiations over a price have since been positive.
Chelsea are expected to pay an initial €80m plus €20m in add-ons for Havertz, who is international teammates with Werner. The deal would represent a coup for Lampard, who was keen for greater quality in attack after losing Eden Hazard to Real Madrid last summer. Ziyech brings creativty after joining from Ajax, Werner scored 34 goals for RB Leipzig last season and Havertz would add a further layer of class.
Although there is some surprise at Chelsea targeting Havertz, Lampard often felt his team lacked cutting edge against negative opponents. Chelsea, who bought Ziyech for £37m and Werner for £47.5m, needed to widen their options in attack after relying on Hazard for so long. Pedro and Willian have left on frees, joining Roma and Arsenal respectively, and Ruben Loftus-Cheek, Christian Pulisic, Callum Hudson-Odoi, Mason Mount and Tammy Abraham remain inconsistent at the highest level and suffered injuries last season.
The need for more depth further up the pitch does not mean Chelsea have forgotten they need to improve their defence. They conceded 54 goals last season and have looked at RB Leipzig’s Dayot Upamecano, Atlético Madrid’s José Giménez, Brighton’s Ben White and West Ham’s Declan Rice. They are also interested in the Atlético goalkeeper Jan Oblak as a potential replacement for Kepa Arrizabalaga.
