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

The Red Devils brought in Bruno Fernandes and Odion Ighalo in the final days of the winter window but are still expected to be active in the summer as they aim to restore their former glories.

Here, Sports Mole rounds up the latest news on possible comings and goings from Old Trafford.

Thursday morning's Manchester United transfer talk news roundup:

Manchester United 'beat Real Madrid to signing of Atletico Madrid starlet'

Manchester United have reportedly completed a deal to sign highly-rated teenage striker Alejandro Garnacho from Atletico Madrid.

The 16-year-old came through the ranks with Atletico and had been playing with their Under-19s side last season.

Atletico's city rivals Real Madrid were also interested in his signature, while Borussia Dortmund were thought to be monitoring his progress too.

However, Marca reports that United have won the race for Garnacho, who is expected to arrive in England to officially complete the deal later this week.

The youngster, who will have to quarantine for 14 days following his arrival, is reportedly set to sign a five-year deal at Old Trafford.

Garnacho is the third Spanish teenager to join United this summer following the arrivals of 16-year-old Marc Jurado and 17-year-old Alvaro Fernandez from Barcelona and Real Madrid respectively.

Manchester United 'preparing fresh Kalidou Koulibaly bid'

Manchester United are reportedly preparing a fresh approach for Napoli centre-back Kalidou Koulibaly.

The 29-year-old has regularly been linked with a switch to the Premier League in recent transfer windows, and Napoli president Aurelio De Laurentiis recently confirmed that he would be allowed to leave if a suitable offer arrives this summer.

Manchester City had been leading the race for his signature, but that deal has been held up by the strained relationship between the two clubs after their Jorginho talks broke down last summer.

Transfer expert Fabrizio Romano, cited by The Mirror, now claims that United are looking to hijack the transfer, which is expected to set them back at least €75m (£68.1m).

United manager Ole Gunnar Solskjaer is known to have earmarked central defence as one of his priorities for the remainder of the transfer window, alongside a new left-back and right winger.

The Red Devils have only made one signing so far this summer, bringing in Donny van de Beek from Ajax.
