Former West Brom boss Robert Di Matteo insists he will have no problems working as number two under new Chelsea manager Andre Villas-Boas.
The Italian, sacked at The Hawthorns in February despite having won promotion the previous season, was unveiled as part of the new backroom staff at Stamford Bridge, where he spent six successful years as a player before injury forced him to retire in 2002.
"It is obviously a challenge for me but I don't anticipate any problems," Di Matteo told the club's official website, www.chelseafc.com.
