The performance of Bobby Zamora under Roy Hodgson particularly have been stellar. The marked improvement in his game have led to numerous calls for an England call up. If the thoughts were that Zamora does not have the big match mentality then those reservations would have been smashed to bits after stunning goals against Juventus and Wolfsburg in the Europa League.
Emile Heskey and Carlton Cole are great as the target and/or link up man upfront but they are not prolific goalscorers. At major world tournaments, goals typically determine how far a nation progresses, hence Bobby Zamora, who is in the form of his life, can provide that secondary goalscoring threat while performing the duties that Heskey and/or Cole does for England.
