Andre Gomes says Everton will benefit from two tough tests against Crystal Palace and Watford.
The Toffees fought for a goalless draw with ten men against Palace last weekend, and grabbed a 1-0 victory over Watford on Saturday.
"These first two results give us strength for the next matches," Gomes told evertontv.
"In the Crystal Palace game with 10 men it was difficult but we were strong to get the point.
"Watford was a difficult battle, a really hard battle. They finished the game with five or six strikers but we did well to hold out.
"Sometimes the game was not brilliant but we won and we are happy with that.
"In pre-season we said we wanted to continue our hard work and the way we are playing at the end of last season.
"At times on Saturday it was a fight and the game was not always good to watch.
"But it was a really good fight and another game with no goals conceded.
"That is really good for us and will give us confidence, so we can look to the next game and try to get three points."
