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.

Sunday morning's Barcelona transfer talk news roundup:

Liverpool winger Sadio Mane 'open to Barcelona move'

Liverpool winger Sadio Mane is reportedly open to discussing a transfer to Barcelona.

At a time when Lionel Messi has requested a transfer away from the Catalan giants, talk may soon turn to who will replace the global superstar.

Barcelona's next move will be dependent on whether they are able to recoup a transfer fee for the Argentine, who currently feels that he should be able to become a free agent.

However, reports in Spain suggest that Mane would like to be considered for a switch to Camp Nou in the future.

While the Senegal international has enjoyed four successful years at Anfield, it is claimed that the 28-year-old will want to take on a new challenge at some point in his career.

The report also indicates that Mane's relationship with Jurgen Klopp 'is not as strong' as it has been in previous years.

Donny van de Beek 'waiting on Barcelona offer'

Ajax midfielder Donny van de Beek is reportedly waiting to see whether Barcelona make a move for him before deciding his future.

The Netherlands international is widely expected to leave Ajax during this summer's transfer window, and both Manchester United and Tottenham Hotspur are said to be interested in his services.

However, according to Sport, Van de Beek is waiting for Barca to make a decision on their transfer plans before agreeing to move to either Old Trafford or the Tottenham Hotspur Stadium.

The report claims that the Catalan outfit are interested in the Dutchman but cannot afford to meet Ajax's £50m asking price, while the Spanish side are currently preoccupied by the Lionel Messi saga.

Van de Beek enjoyed an impressive 2019-20 at club level, contributing 10 goals and 11 appearances in 37 appearances in all competitions.

The 23-year-old's current contract in Amsterdam is due to expire in June 2022.
