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

The Gunners spent more than many expected last summer - most notably their club-record purchase of Nicolas Pepe - but were more reserved in January as they focused on bolstering their defensive options.

Here, Sports Mole rounds up the latest news on possible comings and goings at the Emirates Stadium.

Monday morning's Arsenal transfer talk news roundup:

Leeds United 'given green light to sign Arsenal's Rob Holding'

Arsenal are reportedly prepared to sell central defender Rob Holding during this summer's transfer window.

The 24-year-old has made 78 appearances for the Gunners since arriving from Bolton Wanderers in 2016, although he only featured on 18 occasions during the 2019-20 campaign.

Holding missed an extended period after picking up a serious knee injury in December 2018, meanwhile, and only made eight Premier League appearances last term.

According to the Daily Star, the defender is available for transfer this summer as Mikel Arteta's side close in on a deal for Lille's Gabriel Magalhaes, which is likely to attract the attention of Leeds United.

The Whites are believed to have identified the former England Under-21 international as the ideal player to boost their defensive unit next season on their return to the top flight.

Arsenal would be in a strong position when it comes to any potential negotiations, though, as Holding has a contract at the Emirates Stadium until June 2023.

Ronald Koeman 'makes decision over Philippe Coutinho's Barcelona future'

Barcelona boss Ronald Koeman is reportedly keen to keep Philippe Coutinho at the club this summer.

The Brazil international has struggled to make his mark for the Catalan giants since arriving in a big-money move from Liverpool in January 2018.

The 28-year-old has been in good form for Bayern Munich during the 2019-20 campaign, though, scoring 11 times and registering nine assists in 37 appearances for his loan club.

Coutinho has been strongly linked with a permanent move away from Camp Nou, and a number of clubs, including Arsenal and Tottenham Hotspur, have been mentioned as possible suitors.

However, according to Mundo Deportivo, Koeman is an admirer of the South American and is convinced that he can get the best out of the attacker next season.

The new Barca boss will allegedly meet with the playmaker in the aftermath of the Champions League final in the hope of convincing him to remain in Spain.

Coutinho's existing deal with the Catalan giants still has three years left to run.
