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.

Sunday morning's Chelsea transfer talk news roundup:

Arsenal 'in contact with Willian over potential move'

Arsenal are reportedly still in contact with Chelsea attacker Willian over a potential move to the Emirates Stadium ahead of the 2020-21 campaign.

The Brazil international is contracted to the Blues until the end of the 2019-20 season but his long-term future at Stamford Bridge remains unclear.

Tottenham Hotspur have reportedly offered the 31-year-old a lucrative contract to make the move to North London on a free transfer this summer.

However, according to Bleacher Report, Arsenal are also very much in the hunt for the South American, with the Gunners 'making contact' to determine what sort of deal he is looking for in terms of wages and length.

Willian, who is believed to want a three-year contract at Chelsea, has scored 11 times and provided nine assists in 45 appearances for Frank Lampard's side during the current season.

The versatile attacker has been in English football since arriving from Russian club Anzhi Makhachkala in 2013.

Arsenal boss Mikel Arteta will reportedly only have limited funds to spend this summer due to the financial impact of the coronavirus outbreak, and the Spaniard recently admitted that he had "big concerns" over the size of the club's budget.

Chelsea 'considering signing a new centre-back this summer'

Chelsea are reportedly considering bringing a new central defender to the club during this summer's transfer window.

The Blues currently sit third in the Premier League table, while they will have the chance to book a spot in the FA Cup final when they face Manchester United in the semi-finals on Sunday.

Frank Lampard's side have had their problems defensively this season, though, conceding 49 times in the Premier League, which is only the 11th-best defensive record in the division.

According to Goal, Chelsea 'are increasingly considering' bringing a new centre-back to Stamford Bridge to boost their squad ahead of the 2020-21 campaign.

The report, meanwhile, claims that neither Antonio Rudiger and Andreas Christensen have been offered new deals by the club, which has placed their futures in doubt.

The London club have already secured deals for Hakim Ziyech and Timo Werner ahead of next season, while they also continue to be linked with Leicester City's Ben Chilwell.
