Birmingham City have completed the signing of Maxime Colin on a four-year deal from Brentford.
The 25-year-old moves to St Andrew's for an undisclosed fee, signing a four-year deal which will keep him at the club until 2021.
Colin becomes Birmingham's third deadline-day signing following the arrivals of Harlee Dean and Jota, the latter of whom became the club's most expensive player ever.
In all, Harry Redknapp has now brought in 13 new players this summer, with Colin's deal expected to be the last in the closing stages of the transfer window.
The full-back, who will wear the number five shirt at St Andrew's, spent two years with Brentford, where he scored four goals in 66 appearances.
