Everton boss Roberto Martinez has said that he was pleased with his side's attacking display in their 3-1 pre-season win over Hearts.

Romelu Lukaku netted all three of the Toffees' goals, scoring two from the penalty spot, leading Martinez to express his delight at the progress his team are making ahead of the new season.

"I thought we looked really threatening, very sharp and the link-up play was very good," Martinez told the club's official website. "All over the pitch we had a lot of concentration and showed very good standards.

"It was important to know how to manage a game when you face a team with the energy that Hearts had. I thought we did that very well.

"Going forward we looked a threat, but then we always kept a good balance and only a lapse in concentration early saw us concede from a dead ball situation. Apart from that I thought we kept our defensive duties to a good level."

Everton open their Premier League season against Watford on August 8.
