Birmingham City have officially appointed former West Ham, Portsmouth and Tottenham boss Harry Redknapp as new manager to take over from Gianfranco Zola.

Zola resigned on Monday against a backdrop of mounting pressure after a 2-0 defeat at the hands of Burton Albion saw his record in charge of the Blues extend to a dismal run of just two wins in 24 games, with Birmingham moving quickly to hire 70-year-old Redknapp in his place.

Birmingham had been in playoff contention when Zola arrived in December as a replacement for the controversially sacked Gary Rowett. Now, the club is firmly embroiled in a relegation battle and sits just three points above the drop zone with three games of the season left to play.

For Redknapp, the appointment marks his first job since a short-term stint in charge of the Jordanian national team in March 2016, and his first in club management since a sudden resignation from Queens Park Rangers in February 2015.

Redknapp famously took Portsmouth from the second tier to the Premier League in 2003, eventually guiding Pompey to FA Cup glory and European football in a second spell at Fratton Park. Prior to his Wembley triumph, he had also miraculously saved the club from relegation.
