The right-back has bemoaned the past two losses after a good run put them on course for a finish in the top half of the Premier League.
After a comfortable victory over Manchester United two weeks ago, Everton have suffered defeats to two sides battling to avoid relegation - Aston Villa last weekend before Sunderland's 2-0 victory on Saturday lunchtime.
He is quoted in the Liverpool Echo, saying: “We’ve made no secret of it, it has been a disappointing season but we felt like we got our tails up a bit recently.
“So the last two games have been disappointing.
“We controlled the game for long periods but it’s all about getting the ball in the back of the net.
"It has been one of those seasons and we’re looking forward to finishing on a high now and coming back for pre-season and giving it a real good go – because when we do get things right we are a very good team.
“It is about getting about all over the pitch and not conceding sloppy goals."
There was a poor period especially through the midway point of the season when it seemed as if Roberto Martinez's side couldn't buy a win as they struggled against near enough every side in the league and there were fears they could have been dragged into a relegation battle.
The Toffees are within striking distance of the top half with just the two games remaining, as they are three points behind 10th placed West Ham United. After a recent five-game unbeaten run, the manner of their recent defeats will not please Martinez who is hoping to find the same level of consistency as last season that yielded a record Premier League points total.
He will be hoping for two wins from the final two games to take some momentum into pre-season.
