Everton boss Roberto Martinez says John Stones will learn from their Europa League win at Young Boys.
Everton finished the game with 10 men, as England centre-back Stones was sent off for a professional foul on Young Boys' France international striker Guillaume Hoarau.
Martinez said: "John Stones will learn massively from today's moment. We had to dig deep and defend with 10 men but we still looked like the team with most threat.
"That says a lot about the tactical awareness the players have developed."
