Despite an exceptional amount of success in his short managerial career, the experience of Andre Villas-Boas has been called into question as he starts his new position as Chelsea boss.
Having won a domestic treble and the Europa League during his one season stint with Porto, Villas-Boas already has a CV envied by managers across the globe.
However, aged just 33, and with barely two years as a manager – not to mention never having led a side in the Champions League – some have argued that he does not possess the credentials required to bring European glory to Stamford Bridge.
‘If you’re good enough, you’re old enough,’ goes the old adage, and that would seem to be the case with Villas-Boas, at least that’s the opinion of Chelsea goalkeeper Petr Cech.
"If you are 16 and have the qualities to play at the highest level then that's fine. It's the same for a young manager," Cech told BBC Radio 5 live.
"Villas-Boas won the Europa League [in 2010/11] which showed how good he is.
"He's had a lot of success in the last two years and now he's come back to Chelsea. Hopefully we'll win back the title."
The 29-year-old added: "We have experienced players with a lot of quality,
"I'm sure the players will adapt. Hopefully we'll start well and we'll be successful."
