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

Florentino Perez oversaw a significant overhaul of his squad last summer before focusing more on youth in January. As is always the case with Madrid, though, some of the biggest names in football continue to be linked, even in the wake of the coronavirus pandemic.

Here, Sports Mole rounds up the latest news of possible comings and goings at the Bernabeu.

Sunday morning's Real Madrid transfer talk news roundup:

Bayer Leverkusen chief reiterates Kai Havertz asking price

Bayer Leverkusen sporting director Rudi Voller has denied suggestions that Chelsea are closing in on a deal for Germany international Kai Havertz.

The 21-year-old has been strongly linked with a move to Stamford Bridge over the last few months, and a recent report claimed that the Blues were nearing an agreement with all parties.

However, Leverkusen chief Voller has reiterated that the German giants will not be dropping their valuation - thought to be in the region of £90m - insisting that the coronavirus outbreak does not mean that there will be a summer discount.

"There is nothing new in this regard, and we are still very relaxed about it. Of course, we would be very happy if he stayed for another year. It is clear that the departure of such a player, despite the high transfer fee, always means a loss - see Leipzig and [Timo] Werner," Voller told Sportbuzzer.

"In times of corona, it may actually be that the transfer fees have decreased for many players. But corona or no corona, this is not the case with exceptional players like Havertz or Jadon Sancho. There is no corona discount for them. What makes Kai Havertz so interesting is the fact that he embodies world-class in four or five positions."

Havertz was in impressive form for Leverkusen during the 2019-20 campaign, scoring 18 times and contributing nine assists in 45 appearances in all competitions.

The German - also previously linked with Manchester United, Real Madrid and Bayern Munich - has entered the final two years of his contract at BayArena.

Arsenal 'remain in talks with Real Madrid over Dani Ceballos'

Arsenal are reportedly still locked in talks with Real Madrid over the future of Dani Ceballos.

The 24-year-old spent the 2019-20 campaign on loan with the Gunners, contributing two goals and two assists in 37 appearances in all competitions for Mikel Arteta's side, who ended their season by winning the FA Cup.

A recent report claimed that Zinedine Zidane's team were considering keeping hold of Ceballos this summer as the Spanish giants are not expected to be active in the transfer market.

However, according to Sky Sports News, the Spain international is keen on spending another year with Arsenal and 'talks are ongoing' between the Premier League side and Madrid over a loan deal.

Ceballos could allegedly link up with Madrid as they begin their preparations for the 2020-21 campaign, but a return to the Emirates Stadium is seemingly on the cards.

The former Real Betis youngster has a contract at the Bernabeu until June 2023.
