Jose Mourinho does not believe Chelsea will hold any surprises for him when he returns to Stamford Bridge in the Champions League with Inter Milan next month.
The Portuguese managed the Blues between 2004-2007, twice winning the Premier League, but Mourinho failed to guide the west London team to the Champions League final.
The former Porto boss had an acrimonious parting with Chelsea in September 2007 before arriving at the San Siro in June 2008 to claim the Serie A title in his first season.
And the 47-year-old believes little has changed since his departure having returned to west London in December to watch the Blues take on Fulham.
Mourinho told www.uefa.com: " The last time I was there I was watching all the details with attention.
"Even the warm-up is the warm-up they did in our time. The way they defend set pieces is exactly the same. The position they have on set pieces is exactly the same."
