The buildup to 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.

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

Tuesday morning's Chelsea transfer talk news roundup:

Manchester United to rival Chelsea for Declan Rice?

Manchester United have allegedly identified West Ham United midfielder Declan Rice as a potential summer transfer target.

While Rice is regarded as the biggest asset at the Hammers, there is an inevitably about a future move to a bigger club.

Chelsea have been heavily linked with a move for the England international, who was a boyhood Blues fan and has previously spent time in their youth ranks.

However, according to Football Insider, United are prepared to pay big money for the 21-year-old.

Although United are well stocked for options in central midfield, Ole Gunnar Solskjaer may look to use Rice in the middle of his defence.

Rice still has four years remaining on his contract, leaving West Ham in a strong position regarding the academy graduate's future.

Chelsea line up player-plus-cash bid for Jan Oblak?

Chelsea are reportedly considering whether to launch an approach to sign Atletico Madrid goalkeeper Jan Oblak.

With Kepa Arrizabalaga continuing to struggle for consistency between the sticks, Blues boss Frank Lampard is open to parting ways with the Spaniard.

While a bid for Ajax's Andre Onana is a possibility, The Mirror suggests that Chelsea may look to bring in Oblak as Arrizabalaga's replacement.

Aware that the Slovenia international possesses a release clause well in excess of £100m, the Premier League outfit are keen to include Arrizabalaga in a part-exchange deal.

Nevertheless, despite potentially being able to reduce Oblak's valuation during negotiations, Chelsea may still need to part with at least £70m to get a deal over the line.

Oblak still has three years remaining on his contract at Wanda Metropolitano.
