Owen Coyle is confident Andre Villas-Boas will emerge 'bigger and stronger' for his experience at Chelsea following his recent sacking.
Villas-Boas was dismissed by Chelsea on Sunday after less than a season in charge following a disappointing run of results and claims of dressing room unrest.
The Portuguese became friends with Coyle when the pair took their coaching badges together and the Bolton boss expects Villas-Boas to benefit from his time at Stamford Bridge.
"I spoke to Andre briefly on Sunday after the news had broken," said Coyle.
"I won't say he was shocked because he has worked at Chelsea before and knows how it works. But he was disappointed.
"I have no doubt if he was given the time to see it through, Chelsea would have reaped the rewards and been stronger for many years to come.
"The job he did at Porto was there for everyone to see. But people don't realise what he did at Academica.
"He took a huge risk leaving Inter Milan for a club that was bottom of the league. But he had belief in his own abilities, saved them from relegation and went to the semi-finals of the cup. That was an unbelievable achievement for a young man.
"Chelsea are looking for trophies, who is to say they wouldn't have won one if they had persevered with him?"
Coyle added: "Andre is an outstanding manager and an outstanding man, which is more important in the big scheme of things. He will bounce back.
"We all come into this job with our eyes open, as Andre did. He knew the risks were huge, but so are the rewards.
"He will bounce back bigger and stronger and better for the experience. You have to go through these circumstances to become better."
