Roberto Martinez did point the finger at John Stones in the wake of Everton's 2-1 home loss to Swansea City on Sunday.

The talented centre-half produced an under-hit backpass early in the Goodison Park contest which resulted in goalkeeper Tim Howard tripping Andre Ayew as he attempted to clear the ball.

Gylfi Sigurdsson fired the penalty into the top corner before Swansea conceded down the other end when Jack Cork saw Gareth Barry's flick-on from a corner trickle in off his leg.

But Stones could only watch as he tried to cut out a goal-bound effort from Ayew which deflected off him and over Howard for Swansea's eventual winner but Martinez refused to look at just one individual player for his team's shortcomings.

"I don't think it's just John. It's as a team and it's a situation where we have to deal with a little bit more control," he said.

"Of course, we all know we have to do that aspect a lot better and I don't think there's any need to get punished the way we did.

"It was very unfortunate the team didn't see the player. We should have been aware and should have seen that area better.

"It's day like today where you see how good we can be and how soft we allow scorelines to go away from us. We need to learn from these painful lessons and become a lot better."
