Chelsea have reportedly identified RB Leipzig defender Dayot Upamecano as one of their priority targets for the summer transfer window.
The contrasting performances of the two teams resulted in Lampard openly criticising his players, and it appears as though the Englishman will now attempt to strengthen his backline later in 2020.
According to The Mirror, Chelsea hope to see off the likes of Arsenal in the race for Upamecano, who is expected to leave Leipzig ahead of next season.
The 21-year-old, regarded as one of the best young defenders in Europe, has less than 18 months remaining on his contract with the Bundesliga title challengers.
The France Under-21 international could cost in the region of £50m.
