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

Friday morning's Manchester United transfer talk news roundup:

Manchester United, Tottenham Hotspur want £22m Sergio Reguilon from Real Madrid?

Manchester United and Tottenham Hotspur are reportedly both interested in signing Sergio Reguilon from Real Madrid this summer.

The 23-year-old impressed during his loan spell with Sevilla last season, helping the club to win their sixth Europa League title in addition to finishing fourth in La Liga.

Madrid boss Zinedine Zidane is thought to prefer Ferland Mendy as his long-term left-back option and has subsequently made Reguilon available for transfer, alerting a host of Europe's top clubs.

Chelsea had been heavily linked before instead signing Ben Chilwell in a £45m deal from Leicester City, but a move to the Premier League could still be in the offing for Reguilon.

Marca reports that Manchester United and Spurs are both monitoring the Spaniard's situation, but could face competition for his signature from Italian sides Juventus and Inter Milan, while Sevilla are interested in a permanent deal.

Madrid are expected to demand up to €25m (£22.4m) for Reguilon, who came through the ranks in the Spanish capital but has only made 22 appearances for the first team.

Lionel Messi 'will report to Barcelona training on Monday'

Lionel Messi has reportedly been advised to continue attending Barcelona training for the foreseeable future.

Earlier this week, Messi informed club officials that he wishes to leave Camp Nou this summer, allegedly citing a free transfer clause in his contract.

However, with that option having expired on June 10, Barcelona will rebuff any attempts from the 33-year-old to depart the club without a fee being involved.

Although negotiations regarding an exit are likely to be prolonged, TyC Sports suggests that Messi has been told to continue with business as normal.

The Argentine's legal representatives are said to be want the forward to turn up at training on Monday in a bid to avoid handing Barcelona any leverage behind the scenes.

Messi, who has less than 12 months on his contract, is reportedly attracting attention from Manchester City, Inter Milan, Paris Saint-Germain and Manchester United.
