Manchester City would demand the second biggest transfer fee in football history if Leroy Sane decides he want to joins Bayern Munich.

And with the Blues winger still to indicate what he wants to do, and no formal bids made - despite reports in Germany - the club is confident that they hold all the aces.

But with Bayern talking about a fee of between £90million and £100million, it is clear that the valuation comes nowhere near that of the Blues.

City maintain that they do not want to sell Sane, and will only do so if the player - who has not revealed his intentions - tells them he wants to go.

If Sane does decide he want to return to Germany, City would be looking for a fee in the region of £145million - second only to Neymar's world record fee of £198million.

The Blues have been unhappy at Bayern’s public courtship of the player and have complained to the Bundesliga club, resulting in a public apology.

And they are still hopeful that Sane – who has not told them he wants to go – will eventually put pen to paper on a new deal which remains on the table.

But if Sane decides he wants to go, Bayern will not be getting him on the cheap, with two years left on his current contract.

Sources in Germany were claiming that a £90million bid had been successful yesterday, but City have received no bids for the player.

The market dictates that they would at the very least be looking at the kind of money being demanded for stars like Ousmane Dembele, Joao Felix and Philippe Coutinho.

But given Sane's age, potential, and his superior track record to those other players, they will demand a fee of between 150million and 160million euros - which is roughly £135-145million.

With a month left before the German transfer window closes there has been no move from Bayern - who took the unusual step yesterday of denying a report that they had agreed a £90million transfer for the player.

City want him to stay, but he is concerned about the fact he was a marginal figure at times last season.

But City are far from desperate about wanting to sell the player, while Bayern's need is great - they have lost two world-class wide men in Arjen Robben and Franck Ribery this summer.

By contrast, City are so well-stocked in that department that they have no intention of signing a replacement even if Sane does depart.

Bayern have made it well known that they are interested, without making any formal approach to City – and some of their interest has bordered on illegal tapping up, with hints that they have been in touch with the player.

With president Karl Heinz Rummenigge, coach Niko Kovac and a host of Bayern players past and present making repeated attempts to woo Sane, City have been annoyed.

They contacted Bayern privately to ask them to desist, and the German giants responded by apologising and promising the clamour will stop.

They were especially concerned at a Kovac comment which implied that they had spoken to the player, which is not allowed under Fifa rules.

Kovac said: “Our bosses have shown him a clear plan. We are very focused. Leroy knows what to expect here, and when a player with such capacity comes to FC Bayern, he knows his job.”

But apart from their frustrating at Bayern’s public utterances, the Blues are relaxed about the situation – they feel that the new offer on the table, and the fact that the Premier League is the most attractive league on the planet will be strong influences when Sane comes to make a decision.
