Emmanuel Frimpong has had a corking Twitter bust-up with celebrity Gooner Piers Morgan after the TV host had a dig at the young Arsenal midfielder. Frimpong was sent off in his Premier League debut in the 2-0 defeat against Liverpool at the Emirates yesterday (for a second tyellow following a tackle on Lucas Leiva) and he was in fighting mood when Morgan gave him some grief about his hair-do and his dismissal.
