Photos: Jack Grealish's face says it all after Aston Villa's clash with Birmingham

The 20-year-old played a key role in helping Tim Sherwood's men claim a 1-0 derby victory at Villa Park in the third round of the Capital One Cup.

Rudy Gestede’s second-half header proved enough to earn Aston Villa a 1-0 victory over bitter rivals Birmingham City in Tuesday night’s Capital One Cup third round tie.

Villa are currently in the midst of their worst-ever start to a Premier League season and they struggled to get going through the first half as the Championship side more than held their own.

However, manager Tim Sherwood opted to make a couple of substitutions at half-time which helped change the tide of the game in the hosts’ favour.

Jack Grealish and Jordan Ayew replaced Joleon Lescott and Gabby Agbonlahor and the attacking duo proceeded to open up the opposition defence with their creative passing and movement in the final third.

It was 20-year-old Grealish who ultimately helped create the only goal of the game in the 62nd-minute with a deft ball to Jordan Amavi, who in turn crossed from the left flank for Gestede to slot a thumping header past Blues goalkeeper Tomasz Kuszczak.

Villa had several opportunities to double their lead over the rest of the match but Birmingham also came close to equalising in the 74th-minute, when Jacques Maghoma found himself one-on-one with Brad Guzan thanks to some slack defending from Sherwood’s men.

The 27-year-old winger’s weak shot was easily saved by the American custodian, however, as the claret and blues edged through to the fourth round of the competition while earning bragging rights over their neighbours in the process.
