Frank Lampard insists that the signings of £47.5 million ($60m) RB Leipzig striker Timo Werner and £37m ($46.7m) Ajax playmaker Hakim Ziyech shouldn't unsettle Chelsea's current group after seeing his side suffer another setback away at Sheffield United
The Blues lost 3-0 at Bramall Lane on the same day that Ziyech was pictured in Chelsea's training kit at Cobham Training Centre as excitement grows over the west London club's transfer activity
Along with the two signings already completed the Blues look set to do further business, with £90m-rated ($114m) Bayer Leverkusen star Kai Havertz and Leicester City Ben Chilwell in their sights
Still, Lampard is clear that his current squad has work to do as their latest defeat leaves their Champions League qualification fate in doubt, with Manchester United and Leicester City piling on the pressure
While attention has turned to the Blues' exciting new attacking signings, it is the defence that has come under scrutiny in recent weeks, and Lampard admits he keeps changing personnel due to individual mistakes being made during matches
