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.

Friday morning's Chelsea transfer talk news roundup:

Inter Milan 'willing to use Lautaro Martinez in N'Golo Kante swap deal'

Inter Milan are reportedly willing to use in-demand forward Lautaro Martinez in a swap deal which would see N'Golo Kante arrive at San Siro from Chelsea.

Former Chelsea boss Antonio Conte is understood to have identified a reunion with Kante as one of his top transfer targets this summer as the Milan outfit look to end the Serie A title monopoly of Juventus next season.

The Blues have not categorically ruled out the possibility of cashing in on the France international amid a summer of significant expenditure, but they would demand a hefty fee before considering selling.

Inter are aware that they are unlikely to be able to afford whatever that asking price may be, and Gazzetta dello Sport reports that they have earmarked three players who could be included as part of a deal to reduce the cash outlay.

Martinez, who has been heavily linked with a move to Barcelona, is the most valuable of those being considering by Inter Milan, while Milan Skriniar and Marcelo Brozovic are thought to be the other options.

Inter Milan have also made the trio available for transfer to other clubs in order to raise funds to sign Kante, who was taken to Stamford Bridge by Conte in 2016.

Manchester United, Tottenham Hotspur want £22m Sergio Reguilon from Real Madrid?

Manchester United and Tottenham Hotspur are reportedly both interested in signing Sergio Reguilon from Real Madrid this summer.

The 23-year-old impressed during his loan spell with Sevilla last season, helping the club to win their sixth Europa League title in addition to finishing fourth in La Liga.

Madrid boss Zinedine Zidane is thought to prefer Ferland Mendy as his long-term left-back option and has subsequently made Reguilon available for transfer, alerting a host of Europe's top clubs.

Chelsea had been heavily linked before instead signing Ben Chilwell in a £45m deal from Leicester City, but a move to the Premier League could still be in the offing for Reguilon.

Marca reports that Manchester United and Spurs are both monitoring the Spaniard's situation, but could face competition for his signature from Italian sides Juventus and Inter Milan, while Sevilla are interested in a permanent deal.

Madrid are expected to demand up to €25m (£22.4m) for Reguilon, who came through the ranks in the Spanish capital but has only made 22 appearances for the first team.
