The summer transfer window has now begun, with rumours and speculation continuing to swirl as Chelsea eye possible reinforcements.

The Blues failed to bring in a single player during the January window, despite seeing their transfer ban cut short by FIFA, but have already been busy this summer.

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

Wednesday morning's Chelsea transfer talk news roundup:

Rio Ferdinand claims Chelsea are interested in signing Lionel Messi

Rio Ferdinand has claimed that his friend and former West Ham United teammate Frank Lampard is interested in signing Lionel Messi for Chelsea.

A number of Europe's biggest clubs have been put on red alert after Messi handed in a bombshell transfer request this evening, asking to leave the club he has represented for his entire career so far.

The six-time Ballon d'Or winner, widely regarded as one of the greatest players of all time, could be available on a free transfer due to a clause in his contract, although Barcelona are expected to legally challenge that.

Ferdinand, who also worked as a TV pundit alongside Lampard before the latter moved into the management, has now claimed that the Chelsea boss wants to bring Messi to Stamford Bridge in a blockbuster deal.

Chelsea have already signed Timo Werner and Hakim Ziyech this summer, while deals for Kai Havertz, Thiago Silva, Ben Chilwell and Malang Sarr are also thought to be in the pipeline.

Messi has scored 634 goals in 731 games for Barcelona, helping the club to 10 La Liga titles and four Champions Leagues among a plethora of other trophies.

Thiago Silva 'to undergo Chelsea medical on Thursday'

Thiago Silva is reportedly scheduled to undergo his Chelsea medical on Thursday ahead of a free transfer.

With his contract at Paris Saint-Germain having come to an end, the 35-year-old is contemplating ending his eight-year spell at Parc des Princes.

Despite the French giants allegedly making a last-ditch attempt to convince the Brazilian to extend his stay in France, it appears likely that the veteran will move to Stamford Bridge.

According to Sky Sports News, the centre-back will undergo a medical with club staff later this week.

Given the restrictions in place with regards to coronavirus, tests may be held away from England in order to avoid a mandatory 14-day quarantine period at this stage of the summer.

Having featured for PSG in the Champions League final on Sunday evening, Silva will now take some time off before resuming training next month.
