Welbeck also had scored in midweek for England.
"When he came back from the national team I said 'why do you only score for the national team but you don't score for your club'," said Evra.
"Now he has answered back. I am glad for Danny. He is a striker and he deserved his goals. The second was a great finish.
"Overall, it was a great start.
"We worked very hard in pre-season and even if we had some bad results, the important game was the Community Shield because it was for a trophy.
"Winning that was good for the spirit of the team.
"We accept some compliments for this result but it is only the first game. Now we have to focus on Chelsea."
