Newcastle United boss Sam Allardyce has shrugged off Obafemi Martins' frustrations.

During Sunday's 2-2 draw at Middlesbrough, Martins could not have made it more clear he was unhappy at being substituted for the third game in a row when he trooped off to be replaced by Michael Owen.

He was the first United player on the team bus and when it was pointed out to Sam Allardyce that the Nigerian striker did not look too happy, he told the Evening Chronicle: "That's probably because I brought him off."
