Midfielder, who has been suspended for the last three games, hopes for recall against former club Pompey
Conor Clifford hopes to be given the opportunity to stake his claim again against Portsmouth on Tuesday night, having served his three match ban.
Clifford spent time on loan with Portsmouth earlier in his career, and says Blues will be in for a tough test at Fratton Park.
But the midfielder is hopeful Blues can come through and make it five unbeaten in all competitions, and that he can play a major role in the outcome of the game.
He said: “It has been really frustrating sitting in the stands in recent weeks. Had it happened a couple of games later, I might have only been out for a week, but it feels as though I’ve been out for a month.
“I have had to work really hard in training to keep up my fitness and make sure I’m ready to come back into the side when I’ve served my suspension.
“You always approach training slightly differently because you know you won’t be playing on the Saturday, so I’ve been doing some extra running after sessions.
“It’s great to be back available and I have had a spring in my step the last couple of days because I know I can play again against Portsmouth.
“Obviously I may not go straight back into the side but if I do it is really important to take my chance because there’s really good competition for places.
“The likes of Anthony Straker and Michael Timlin have come into the side and really earned their place for the next game so that is what I hope to do.”
Clifford doesn’t think a big crowd at Fratton Park will have a negative impact on Blues, and says the confidence among the squad is fantastic.
He said: “Pompey aren’t enjoying their best form at the moment but it is always a tough place to go. The fans there are fantastic, I remember that from my short time there.
“But what is important is that we just play our game. The lads have done really well in the last few games and we’ll need to be at our best again against Pompey.
“You never know with this league, but if we can really put a run together now I’m sure we can be right up at the top of the table over Christmas.
“Confidence is really high at the moment and we want to keep it that way. I’m looking forward to hopefully playing against my former club and picking up the three points.”
