The summer transfer window is in full swing and this is the time of the year when the rumour mill goes into overdrive.

That is epitomised by the latest round-up of transfer news and gossip which includes Manchester United, Monaco, PSV and a bizarre move for one-time Burnley target Gary Cahill.

We've reviewed all of the gossip from the continent - and given you our verdict.

Man Utd 'submit transfer offer' amid legal dispute

Manchester United have made a bid to sign French wonderkid Hannibal Mejbri amid a legal dispute over his Monaco contract.

The 16-year-old wonderkid appealed to Ligue de Football Professionnel to have his contract terminated after receiving a big offer from the Red Devils.

He argued his first deal was not properly ratified due to him putting pen to paper when under the age of 15 - but RMC Sport report the lawsuit was rejected as Monaco cannot be penalised twice for the same offence.

Likelihood: Quite a bizarre one, that. Hard to weigh in on, given the legal issues surrounding it, but it would be a fresh change in approach for Manchester United.

Man Utd 'eye Dumfries transfer'

Netherlands international Denzel Dumfries has been identified as a solution to Manchester United’s issues at right-back, according to The Sun.

Having seen bids to sign Aaron Wan-Bissaka rejected, United have been forced to explore other options which has led to their discovery of the PSV full-back.

Dumfries is a cheaper alternative to than Wan-Bissaka, with a £25m fee thought to be enough for United to get their man.

Likelihood: It's hard to see them moving on so quickly from Wan-Bissaka - who seems such a perfect fit - so we take this one with the usual pinch of salt.

Shock Inter move for Cahill?

Gary Cahill could be set for a reunion with Antonio Conte.

Cahill is set to be a free agent when his contract at Chelsea expires at the end of this month and has already been linked with a switch to Villa Park.

But Inter are also tracking the veteran centre-back, according to Italian broadcaster Sport Mediaset.

Likelihood: Looks like classic 2+2=5 stuff from Italy, to be honest.
