Chelsea boss Jose Mourinho has insisted there is no rift between himself and the club's academy director Frank Arnesen, either personally or professionally.
The pair were reportedly at odds with each other after Mourinho's attempts to add to his squad during the January transfer window were blocked by Roman Abramovich.
Mourinho was forced to play youngsters Lassana Diarra and John Obi Mikel when injuries began to mount up at Stamford Bridge over the winter months.
However, the Portuguese tactician is pleased with the final outcome with just one defeat since November and likes of Diarra and Mikel gaining valuable experience.
"There is no conflict between me and Frank Arnesen," Mourinho said.
"He has his job and I have my job. I would be very stupid not to use his structure. When we have 40 or 50 scouts around Europe for the use of football, I would be very stupid if I don't use his people and structure to help me in my job.
"I have no personal problems with him. He is not a 'yes' man, so he does not say yes every time I want him to say yes. But the relationship is positive and I have no problems working with him.
"December and January was a big problem for me because we had too many injuries and I was desperately needing at least one defensive player to give my team the balance it needed at the time.
"We didn't. But after that I spoke positively and the team closed ranks. We fought and because of that fight in the difficult circumstances we had the team became stronger and gave us a chance to promote kids like Mikel and Diarra.
"If you buy players in January almost for sure, Mikel and Diarra would not have had the chances they have had."
