David Moyes has warned West Ham United to be aware of any 'dark arts' tactics employed by Sevilla in their Europa League last-16 second leg on Wednesday.
The Spaniards head to London Stadium with a 1-0 advantage after the first leg.
And Moyes wants his side not to fall for any poor sportsmanship shown by the opposition.
When asked if he is a fan of the dark arts, Moyes said: "I'm not. This is a gentleman's sport.
"In some way we're all desperate to win and we'd kick your granny, if you know what I mean, to try to get a result.
"But in the same breath, I think behind it all, you want to win in a fair and correct fashion. We know it will be a difficult night."
