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.

Sunday morning's Chelsea transfer talk news roundup:

Chelsea 'closing in on Ben Chilwell signing after breakthrough in talks'

Chelsea are reportedly on the verge of signing Ben Chilwell after making a breakthrough in talks with Leicester City.

The Blues, who have already brought in Timo Werner and Hakim Ziyech ahead of next season, have made signing Chilwell their top defensive priority.

Following weeks of talks with tough negotiators Leicester, The Times claims that a price has finally been agreed between the clubs.

The report indicates that Chelsea may have to hand over a record sum for a left-back to get the deal over the line.

England international Chilwell has spent four seasons in Leicester's first team, making 120 appearances since the start of 2016-17.

Manchester United have also been credited with an interest in the 23-year-old defender.

West Ham United 'reject swap deal with Chelsea for Declan Rice'

Chelsea have reportedly had an audacious swap deal for Declan Rice rejected by London rivals West Ham United.

The Blues are keen to bring in the seven-cap England international this summer, but United are said to value him at £80m.

With a straight-cash offer not being considered, The Times claims that West Ham were offered both Michy Batshuayi and Ross Barkley in exchange.

However, the Irons supposedly rebuffed the proposal and have told Chelsea to pay up the full amount if they wish to land their man.

The same report suggests that Frank Lampard intends to convert holding midfielder Rice into a centre-back should he eventually join Chelsea, though that is looking increasingly unlikely.
