Big-spending Nottingham Forest are ready to add to their army of players this month as Steve Cooper revealed Jesse Lingard faces a month out of action.

Manager Cooper believes the club will make every effort to bolster his squad ahead of a push to secure Premier League safety.

Forest made 21 signings in the last transfer window, during the English summer, with free agent Serge Aurier later joining the flood of arrivals after the deadline passed for deals between clubs.

It was an extraordinary burst of activity from the promoted team, back in the English top flight for the first time since 1999, and they are determined to ensure it is not a one-season return to the elite.

After Sunday's 1-1 draw against Chelsea, in which Aurier scored, Cooper was asked about the prospect of making new signings, and he said: "I think so, hope so.

"I trust in the club to get to work, and if there are some things that can help the squad and the team and what we need, then we will do that.

"You say it a little bit through gritted teeth, because of what went on in the summer, and there's that sense of Forest signing players again, but the summer was the summer, you have to look at where we're at now."

Forest sit 18th in the 20-team Premier League, with three sides to be relegated.

Cooper confirmed former Manchester United and England midfielder Lingard will be unavailable for a stretch of fixtures due to a hamstring problem.

"We've picked up some long-term injuries since the summer to key players. Jesse's out for a month now," Cooper told Sky Sports.

"If we can add the right players in the right positions, then we'll need to do that, and we'll want to do it as well."
