There will not have been any self-congratulation or back slapping in the Stamford Bridge office in which director Marina Granovskaia does her negotiating when Callum Hudson-Odoi signed his new Chelsea contract.

Chelsea finally announced Hudson-Odoi’s new five-year contract worth £120,000 a week on Thursday evening to complete what has become the unlikely feel-good story of the summer.

But just as she did not lose her cool when Eden Hazard delivered the news she and Chelsea fans had dreaded, when the Belgian informed her that he would not sign a new deal and wanted to move to Real Madrid, Granovskaia will not be getting carried away with the celebrations over Hudson-Odoi.

Keeping a level head is one of Granovskaia’s biggest assets, according to those who have dealt with her regularly. Congratulatory messages are often said to be met with a note of caution, while bad news is viewed as part of the job.

Real and Bayern Munich can testify to the fact that it is also pointless trying to panic Granovskaia. The Spaniards had hoped to land a relative bargain in Hazard, but quickly agreed to a deal worth up to £130million for a player entering the final 12 months of his contract.
