Porto coach Andre Villas-Boas may face a battle winning over the senior players at Chelsea.

Villas-Boas was a coach at Stamford Bridge under Jose Mourinho.

The Daily Mail says accepting Villas-Boas as their manager could take the Chelsea players some time. After all, he was the guy who handed out the DVDs, once had a scrap with Frank Rijkaard and didn't seem to be any older than they were. He is actually the same age as Didier Drogba and Frank Lampard, who celebrated his 33rd birthday on Monday.

He was brought in at Chelsea by Mourinho to deliver detailed information on the opposition, providing every player with a video with specific information about their direct opponent as well as the team in general.

Now, however, he is about to be presented as the replacement for 52-year-old Carlo Ancelotti, a double Champions League winner with AC Milan and domestic double winner in the first of two seasons at Stamford Bridge.

One Chelsea insider said: "Andre is very clever and fluent in English but I have to say I never saw him as a future Chelsea manager."
