Debutant Marcel Oakley scored 15 minutes from time as Birmingham beat League Two side Colchester United.

The 18-year-old right-back's deflected shot beat Shamal George to secure his side a place in the second round of the Carabao Cup.

Riley McGree came close to scoring Birmingham's second five minutes later, but his shot was palmed away.

For the visitors, Sylvester Jasper posed a constant attacking threat and twice fired wide.
