The summer transfer window has now closed, shutting the door on one of the most turbulent spells in Barcelona's history.

The Spanish giants were rocked by Lionel Messi's request to leave the club, sparking a bitter contract dispute which ultimately ended with the six-time Ballon d'Or winner reluctantly agreeing to stay for at least another season.

Other notable names such as Luis Suarez, Ivan Rakitic and Arturo Vidal did leave, though, while Messi's future is sure to be the subject of much more speculation going forward.

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

Wednesday morning's Barcelona transfer talk news roundup:

Barcelona, Real Madrid 'to battle for Hoffenheim starlet'

Barcelona and Real Madrid have reportedly emerged as the frontrunners to sign Hoffenheim youngster Melayro Bogarde.

The 18-year-old has made three appearances for the German outfit this season, helping his side to clean sheets in their double-header against Slovan Liberec in the Europa League.

While the teenager is in line to earn more opportunities, the Dutchman has just seven months remaining on his contract.

As well as Barcelona, Aston Villa, Borussia Dortmund and Ajax have all been linked with a move for the prospect ahead of the January window.

However, according to Sport, it is Barca and Real Madrid who are regarded as Bogarde's most likely destination in the future.

Given the financial situations at Camp Nou and the Bernabeu, the Spanish giants see value in negotiating a cut-price deal as soon as possible.

Chelsea 'leading race for David Alaba'

Chelsea are reportedly prepared to make an approach for Bayern Munich defender David Alaba during the January transfer window.

Despite remaining as a key man at the Allianz Arena, Alaba's contract is due to expire in 2021, which has naturally led to widespread interest in his signature.

Liverpool, Manchester City, Real Madrid and Barcelona were all linked with a move for the Austria international during the summer.

However, according to AS, Chelsea could make a formal bid in January, despite the 28-year-old being available on a free transfer later in 2021.

The report suggests that the Blues want to tempt Bayern into a sale for a cut-price fee, rather than giving the Champions League winners more time to agree fresh terms with the player.

Negotiations between Bayern and Alaba have allegedly come to a halt with Bayern unprepared to meet his wage demands.
