WAR! Ashley Cole versus Arsenal fans!

Ashley Cole joined Twitter on Sunday, and he's already used the social networking site to have a pop at former club Arsenal.

Within 12 hours of joining the site the Chelsea defender replied to taunts from Arsenal fans, among them Piers Morgan, by boasting about the number of trophies he has won since leaving the Emirates for Stamford Bridge in 2006.

Fans of the Gunners bombarded Cole's profile with abusive tweets as soon as the England left-back joined the site, as many of the Arsenal faithful have struggled to forgive Cole for his move to their London rivals.

Cole has won 11 major club trophies in his career, and he responded to the taunts with a boast of his own.

He gloated about the fact that, while Chelsea had won a number of competitions since 2006, Arsenal had won nothing in the same period.

In fact Arsenal haven't lifted any silverware - of any note - since beating Manchester United in the 2005 FA Cup Final, a fact which Cole seemed to enjoy reminding fans of his former club.

He tweeted: 'I am what I am!!! Winnerrr!!!! Hahahahahahah, 11 to me 0 for you!!! http://yfrog.com/h7i4jsoj'

Accompanied with a photograph of him in the dressing room in Munich after Chelsea's Champions League triumph in May.

He then tweeted to Morgan, who had called the defender 'Cashley' in reference to him leaving Arsenal for a pay hike at Chelsea.

Accompanied with a mocked up graphic of all seven trophies Cole had acquired whilst in Chelsea blue.

Alongside the Arsenal crest is a sparse blue space, denoting how many trophies the Gunners have won in the same time period.

Cole later tweeted of those he repeatedly gloated at: 'tut tut tut, love to give it out but cant take it when the truth is told, babies!!!! thought people on here had sense of humour!!!!!'

He also used the site to interact with football friends Wayne Rooney, Joleon Lescott and Nigel de Jong, and tweeted a photo of Chelsea stretching in Central Park earlier on Sunday.
