William Gallas has slammed former Arsenal team-mate Samir Nasri, claiming the midfielder's outburst at a journalist following France's Euro 2012 exit has revealed his true character.The French pair have been involved in a long-running war of words since the 25-year-old allegedly refused to give up his seat for legendary striker Thierry Henry on Les Bleus' team bus at Euro 2008.Gallas reportedly accused his compatriot of a lack of respect and the players are believed not to have spoken during their time together in north London.And now, following Nasri's angry tirade in which he offered to fight a reporter after his side's Euro 2012 quarter-final loss, the Tottenham stopper insists observers will sympathise with his position.
