Barcelona coach Tata Martino is delighted with their start to the season.

A 4-0 thrashing of Rayo Vallecano at the weekend came on the back of an identical scoreline against the Dutch giants in midweek, allowing Martino to match the impressive start of his predecessor Tito Vilanova last season.

Few would bet against them adding another success at home to Real Sociedad on Tuesday and Martino is seeing signs of improvement in his team.

"I believe we are getting better," he said. "I would like to keep going along the way we played in the second halves against Ajax and Rayo. I feel we are getting there.

"I see the players more comfortable each day and think we are improving all the way. We have a perfect amount of points but are not close to perfection in our performances. We can keep improving; there are a lot of things we can do better."
