Bosingwa believes the club's young generation of stars are in the right hands.
“Frank was maybe the best professional I ever played with in my life, so I had no doubts over his abilities as a coach and the commitment he would show.
“He will give them the confidence and power to make Stamford Bridge a real force not just in England again, but in Europe.
“The atmosphere at the Bridge was incredible, especially on European nights.
“Every player wants those moments in Europe and your focus suddenly goes up 200 per cent. But what Frank can add on top of that is to let them be free and embrace the pressure."
