Gary Rowett's men are currently six points adrift of the top six.
Birmingham City captain Michael Morrison believes that the Blues will need to collect at least five wins from their remaining nine games if they hope to secure a play-off spot in the Championship this season, the Birmingham Mail reports.
Gary Rowett's men's hopes of sneaking into the top six have taken a dent in recent weeks as they have not won in their last three games. Nevertheless, Morrison is confident that they can catch the teams that currently occupy those coveted places in the division.
"I think we will need at least five wins, without a doubt - and then hope that's enough because Sheffield Wednesday and Derby are both good teams," he told the Mail.
"They seem to have got themselves a little more settled at Derby now. It will be a tough task.
"We have got to worry about ourselves. If we don't get in and we have won five or six games in the run in there's nothing more we can do."
Although they currently find themselves six points adrift of the Owls, who sit sixth in the table, they have a small advantage over the four teams above them in that they have played a game less so will have the chance to close that gap, and potentially leap ahead of both Ipswich and Cardiff.
And with three of the top six, as well as the Bluebirds, still to play before the end of the regular season, Rowett's side will know that picking up victories in those games will give them huge amounts of confidence which could prove crucial if they manage to extend their campaign as they may have to get past two of those sides once again if they hope to earn a place in the Premier League.
