Clint Dempsey rips up referee's notebook and sees red

Clint Dempsey joined Seattle Sounders from Tottenham in August 2013

Clint Dempsey ripped up a referee's notebook and was sent off as Seattle Sounders finished a cup match against Portland Timbers with seven men.

The United States captain reacted angrily to a red card for team-mate Michael Azira during a US Open Cup tie.

Referee Daniel Radford sent off the 32-year-old forward as well as Azira, having earlier dismissed Brad Evans.

Dempsey flicked the notebook out of Radford's hand, picked it up off the pitch and then tore it into pieces.

Striker Obafemi Martins also went off injured with all three substitutions used as Seattle lost the game 3-1.

Dempsey, who left Tottenham and returned to Major League Soccer with Seattle in August 2013, was dismissed in extra time at the Starfire Stadium.

After the red card Dempsey, capped 112 caps by the US, had to be restrained by team-mates and sarcastically applauded in the face of an assistant referee as he made his way off the pitch.
