England boss Gareth Southgate says his side's opening European Championship win over Croatia will "relieve some tension" in his squad.
It is the first time England have won their opening game at the tournament.
Raheem Sterling scored the only goal in front of 22,500 fans at Wembley after being set up by Leeds midfielder Kalvin Phillips.
"You know if you don't win the first game, the pressure ramps up," Southgate told BBC Radio 5 Live.
"We have two really difficult games left in this group and we made a good step forward today, but [there are] important steps to go to qualify.
"I'm most pleased with the performance. Of course the win is important. It was a big occasion, a sweltering hot day and the players settled really quickly, used the ball well and we limited Croatia to very few clear chances throughout the game."
