Plenty of Birmingham City fans have taken to Twitter to react to the news that the club's upcoming FA Cup fourth round tie with Coventry City has now sold out for away supporters.

As confirmed by the Blues' official website, all 9,260 tickets available for the clash have now been purchased by supporters.

Whilst Coventry have sold around 9,500 tickets for the game as of yesterday, the capacity at St Andrew's is 30,009.

Although Birmingham will be the away team at their own stadium for this fixture due to the nature of the FA Cup draw, the Sky Blues have agreed to a near 50:50 split when it comes to tickets.

Yet with over 10,000 tickets in total yet to be sold, it will be intriguing to see whether the Blues opt to ask Coventry for more supply ahead of Saturday's showdown.

Having failed to reach the fifth round of the FA Cup since 2012, Birmingham will be determined to secure their progress in the world's oldest domestic knock-out competition by beating the Sky Blues.

Although the Blues will enter the clash as favourites due to the fact that they play in a higher division than Coventry, they cannot afford to underestimate their opponents who are currently thriving under the guidance of manager Mark Robins.
