“You scrutinize at the squad they acquire, the changes they can produce, the team they can start with, they acquire players all over the pitch who can produce a inequity and we acquire to be ready for that.
“I never pay any attention to any context around a team we play against apart from them being at their best because I always reflect you acquire to prepare for that.
“That’s what we’ll be doing. We want to recede there with our best intentions of getting a result we really need and want. We acquire got to know what it takes from our guys to finish well and try and minimise the strengths they acquire because there is a lot.”
Forest will give Serge Aurier every chance to be fit after he limped off in Monday night’s win over Southampton with a knock.
