Chelsea's addition of Kurt Zouma was confirmed on deadline day, proving that while Jose Mourinho was insisting publicly there would be no deals, behind the scenes he was working away.
The defender was loaned back to Saint-Etienne for the rest of the season, and will join up with his new teammates in July, but appears thrilled at the opportunity.
In an interview with French television station BeIN Sport, he spoke of how the Chelsea boss convinced him to sign up.
"Mourinho called me personally to tell me that he wanted me at Chelsea.
"When I heard those words I jumped at the chance. Both clubs have been in contact and now I'm happy.
"Mourinho is a great coach that I loved since the first adventure at Chelsea, and when I had the opportunity to sign for the Blues I was really happy."
Zouma, 19, is already a French international and is expected to go to the World Cup next summer.
He is now back in action, playing the last two games for the club, after serving a 10-game ban for injuring an opponent in late 2013.
Saint-Etienne are yet to concede a goal in the two Ligue 1 games he has played since his comeback, and it's widely regarded Chelsea have secured a gem.
The club should be glad they have a manager with the pulling power Jose Mourinho has when it comes to transfers. There are few players in the world who would surely turn down the chance to join the Blues if the boss comes calling.
