I think Sol Campbell joining Arsenal is good thing....He may not be the player who used to keep the Arsenal back line in check but he is still a decent signing for us. I don`t expect Sol to be Arsenal`s savior in times of need but he would be of some help in directly taking the places of Gallas or Verma in case of injury and fatigue...With injury-prone Silvestre and with hot-cold Sendy, Sol would be a consistent performer should Arsene choose to play him...I am pretty sure that Sol would want to impress seeing that the World Cup is fast approaching... He is no leader but he is a decent player...
