Bayer Leverkusen coach Robin Dutt is surprised by the pressure Chelsea boss Andre Villas-Boas is experiencing.
Bayer host Chelsea tonight in the Champions League.
Dutt said: "He has achieved quite a lot with Porto and, if Chelsea pay 15 million euros for a coach, they must consider it worth it.
"He's well respected, has made a good reputation, and his quality is there to see. He'll do well at Chelsea."
Leverkusen can only dream of paying £13million for a manager or £50million for a striker, as Chelsea have done in 2011.
Dutt said on Wednesday: "The finances in England are completely different to over here, and Schalke reaching the semi-finals (last season) was a huge achievement.
"In Germany, the game's more efficiently run. Chelsea have a 'world' squad. We have to beat the money tomorrow."
