Campbell was recalled to the national team. He played four matches under McClaren as England's qualification campaign failed. New head coach Fabio Capello did not select Campbell for his first squad in January 2008. Campbell enjoyed a fine run of form on his return to Arsenal and had retained hope of making it to England's squad for the 2010 World Cup, which would have been his fourth outing on the world stage along with a record seventh major tournament for his country. However, he was not named in Capello's 30-man preliminary squad, with the coach opting instead for Carragher and King among others as potential defensive cover for Ferdinand and Terry. Style of play Regarded as one of the best English centre backs of his generation, Campbell was a strong, athletic and imposing defender, with a good positional sense, and was also a strong tackler. Due to his height and physical power, he excelled in the air, both offensively and defensively, although he initially had to work hard to improve his heading ability during his teenage years. He did not possess good natural stamina, but had pace, power, agility and quick feet, as well as significant mental strength. Due to his versatility and range of skills, as well as his ability to carry the ball out of defence and get forward, he was also capable of playing as a right back on occasion. However, despite being fairly comfortable in possession, he frequently drew criticism throughout his career for his poor distribution.
