Watford manager Quique Sanchez Flores says his team are ready to take on an unpredictable Chelsea side at Stamford Bridge on Boxing Day.
The Blues are preparing for their first game under new manager Guus Hiddink, who watched from the stands as they recorded a 3-1 win over Sunderland last weekend.
"Of course when a club changes their manager, the players need to show for the new manager their skill, power and energy," Flores said. "We are ready to face this experience, we know they will try to look like a very tough team.
"For us it is not valid what we know about the Chelsea of Jose Mourinho, for us it's important to know what happened against Sunderland because they are the first lines of Hiddink. That's what we can analyse, nothing more.
"Of course we are expecting a tough game because they play well, they have experience, a lot of quality. We know that we have had a good run, but the feeling within the dressing room with the players is that it is no surprise for us."
The Hornets have been on a little winning streak with four consecutive victories, the most recent and most impressive of which was a 3-0 triumph over Liverpool last time out.
"We work with the idea that to win a match is something normal, it's not like a big surprise to win, win and win again," the Spaniard added.
"The mentality in the big clubs always is the same. You are used to winning and you want to win again. So to translate this mentality for a team like Watford, who are just promoted, it's very important to instil this kind of mentality."
