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

The Spanish champions spent big on Antoine Griezmann last summer but missed out on a big-name striker in January and have been hit hard by the coronavirus pandemic, meaning that selling players rather than buying could be their priority this summer.

Here, Sports Mole rounds up the latest transfer news from the Camp Nou.

Friday morning's Barcelona transfer talk news roundup:

Tottenham Hotspur 'make official bid for Antonio Rudiger'

Tottenham Hotspur have reportedly made an offer for Chelsea defender Antonio Rudiger.

The Germany international is allegedly surplus to requirements at Stamford Bridge and is expected to leave Frank Lampard's side before the transfer window closes on October 5.

A number of clubs, including Paris Saint-Germain and Barcelona, have been mentioned as potential suitors for Rudiger, who has made 115 appearances for the Blues in all competitions.

However, according to Italian journalist Nicolo Schira, Spurs have now lodged an official bid for the 27-year-old as Jose Mourinho's side look to bring another centre-back to the club.

Schira claims that Tottenham are keen to loan Rudiger for the 2020-21 campaign but also want the option of signing him on a permanent deal next summer.

The German is yet to make a single appearance for Chelsea this season and has not even been on the bench for Lampard's side since their opening game of the new Premier League campaign.

Barcelona 'offer Manchester City Rafinha in Eric Garcia deal'

Barcelona have reportedly offered Rafinha to Manchester City as part of a deal for Eric Garcia.

The Catalan giants continue to be linked with a move for Garcia, but it is understood that Ronald Koeman's side are some way off coming to an agreement with the Premier League outfit.

City are believed to want €30m (£27.2m) for the teenager, but Barca are only prepared to offer €10m (£9m) for a player who will be out of contract at the Etihad Stadium next summer.

According to RAC1, the La Liga giants have now offered €10m (£9m) for Garcia but are also prepared to include Brazilian attacker Rafinha as a makeweight.

The report, though, claims that City are unlikely to accept the terms as they are looking for a straight cash deal and would not be interested in Rafinha due to their current midfield options.

The 27-year-old is back at Camp Nou this summer after another loan spell at Celta Vigo.
