Chelsea boss Frank Lampard has insisted his squad will not become unsettled if new signings arrive at the club this summer.

The Blues have already made moves in the transfer market to sign Ajax winger Hakim Ziyech - who began training with his new team at their Cobham training complex this week - and Germany international Timo Werner from RB Leipzig.

Lampard has also been linked with potential swoops for Bayer Leverkusen starlet Kai Havertz, West Ham captain Declan Rice and Leicester City defender Ben Chilwell.

The need for more defensive reinforcements was highlighted after costly mistakes in the dismal 3-0 defeat by Sheffield United, with Chelsea now conceding 49 goals in 35 league games.
