New players were necessary - O'Driscoll
Forest manager Sean O'Driscoll admitted it "was blatantly obvious" his squad was in need of some serious strengthening before the start of the new season.
O'Driscoll looked on as his side conceded a two-goal lead to draw 2-2 with local rivals Notts County - David McGoldrick's effort and Lewis McGugan's penalty were cancelled out by Magpies pair Alan Judge and Yoann Arquin - and the Reds boss said his defence was in need of a boost.
"We cobbled together a back four in the second half and it made a difference, but the attitude was first class and we'll take one or two positives out of it," he said.
"It is blatantly obvious that there are still gaps in the squad. My right-back was a central midfield player, another central midfield player was in the centre of defence and we drafted one of the young lads in at left-back.
"On top of that we had an 18-year-old, who is not the most experienced, who we were asking to lead the back line. That was always going to prove difficult and they exploited that lack of knowledge and experience.
"But they will learn from the experience. They have to. There is no point in playing pre-season games if you're not going to learn from them. We'll take the positives out of this."
