Everton attacker Steven Naismith says they won't take Europa League opponents Young Boys lightly.
Everton host the Swiss defending a 4-1 first-leg lead.
But Naismith told the Liverpool Echo: "To be honest, there hasn't been any chat of the last 16 because we know how cup competitions can work and how quickly things can change.
"We've given ourselves a very good chance after a very good performance and we deserve to be where we are, with a three goal advantage, but the second leg will be about doing a professional job and trying to play as well as we did out there, score more goals and cement our place in the next round."
