Arsenal Double-winning captain Frank McLintock has likened Alex Song to former teammate Peter Storey.

Song is now perceived as a vital member of Arsène Wenger's first-team, especially now the manager has adopted a 4-3-3 formation.

"When they have three in the centre of midfield and they leave Van Persie up front, it's making us stronger in midfield," McLintock told Arsenal.com.

"We always played 4-4-2 with Peter Storey as the anchor man in midfield and he was very protective of the back four. Song is one of those players who can do the same kind of job as Peter Storey. Peter ended up with about 20 caps."
