Calderwood remains unruffled by calls for him to go (Getty Images)

Nottingham Forest manager Colin Calderwood says he is not too concerned about his future, despite a run of only one win in the last seven matches.

The Reds have slipped to fifth place with a play-off spot still not guaranteed, and supporters have chanted for his removal at recent matches.

Forest go to second-placed Carlisle on Tuesday, and Calderwood is hoping his future as manager is not on the line.

"It's not something that overly concerns me if I'm honest." he said.

Interview: Forest boss Colin Calderwood

Calderwood is in his second season in charge at the City Ground, and led Forest to play-off failure last season.

Don't let the disappointment affect you Colin Calderwood

This time around, despite being in a good position for much of the season, the Reds have stuttered over the last few games, culminating in a disappointing defeat at Doncaster on Friday.

That defeat effectively ended Forest's hopes of automatic promotion, which Calderwood admits was a blow, but now he wants to see a reaction from his players.

"Don't let the disappointment affect you," he told BBC Radio Nottingham, "it's the next stage we've got to affect."

That next stage sees the Reds go to Carlisle, followed by a home game against Cheltenham at the weekend, and with clubs fast catching them in the play-off race, Calderwood wants to secure that top-six place as soon as possible.

"Ideally we do it quickly. Go and get the points on the board and then focus on the last two or three games of the season."

And the manager seems to accept that his position will be under threat if the Reds fail to go up this season: "We've obviously got to go and try and win promotion," he said.

"The best chance is to be in the top two, but whatever way it is we will have to do it."
