Croatia boss Zlatko Dalic hopes his side can summon the energy to beat England in the Nations League after a late victory over Spain.
Sunday's Wembley contest is a League A Group 4 decider, which could seal pool victory, or demotion from the top tier of UEFA's new event.
Dalic said: "We totally respect the England team. We learned a lot in both matches.
"I'm more worried about our team because we played against Spain two days ago.
"I'll try to get the best from my players."
Thursday night's 3-2 win over Spain in Zagreb means plenty is at stake for the 2018 World Cup finalists, who beat England in extra-time of the semi-final in Russia.
Croatia will reach the Nations League finals with a win or scoring draw, but will be relegated with a loss or goalless draw.
"We don't need to be motivated," Dalic added. "We play at Wembley, one of the most important stadiums in the world."
If the result goes Croatia's way it is England who will be relegated from League A Group 4.
Croatia had not scored in the tournament prior to the win in Zagreb.
Ivan Perisic said: "Maybe it was too soon after the World Cup. That's why there was a little bit of a comedown.
"Tomorrow we will play how we know we can play. We will be very focused on the next Euro qualifiers but tomorrow against England we will try to play like we did against Spain."
