Chelsea have already signed Hakim Ziyech and Timo Werner this summer as they build towards the start of the 2020-21 Premier League campaign, which begins in the middle of September.

The club's transfer business is not expected to stop there, though, with head coach Frank Lampard thought to be targeting a number of new players in the market.

Here, Sports Mole rounds up the latest news on possible comings and goings from Stamford Bridge.

Friday morning's Chelsea transfer talk news roundup:

Willian 'agrees three-year contract at Arsenal'

Chelsea attacker Willian has reportedly agreed a three-year contract with Arsenal worth £100,000 a week.

The speculation surrounding the Brazil international's future continues to gather pace with his contract at Stamford Bridge due to expire later this month.

According to ESPN, the experienced attacker has now agreed a three-year deal with the Gunners, and a move is expected to be announced before the end of August.

The South American has been in strong form for Frank Lampard's side this season, scoring 11 times and contributing nine assists in 47 appearances.

Chelsea 'to prioritise Jose Gimenez over Declan Rice'

Chelsea are reportedly prepared to prioritise a deal for Atletico Madrid defender Jose Gimenez.

The Blues are expected to bring at least one new centre-back to the club during this summer's transfer window, having struggled in that area of the field during the 2019-20 campaign.

West Ham United's Declan Rice has been strongly linked with a return to the club. However, according to Football Insider, club officials would prefer to get a deal for Gimenez over the line.

The report claims that Gimenez could be available for £60m, which would likely make him a cheaper alternative to Rice, who excelled for West Ham in the latter stages of the 2019-20 campaign.

Chelsea make progress in race to sign Real Madrid defender Sergio Reguilon?

Chelsea have reportedly emerged as the clear frontrunners to sign Real Madrid defender Sergio Reguilon during this summer's transfer window.

Everton have been strongly linked with the Spaniard, who spent the 2019-20 campaign on loan with Sevilla.

However, according to ESPN, the Blues have already held discussions with Los Blancos regarding a deal, with a season-long loan or a permanent deal worth £22.5m both options.

Frank Lampard's side could lose both Marcos Alonso and Emerson Palmieri this summer, meaning that a new left-back is likely to be a priority ahead of next season.
