Chelsea host Forest on Monday afternoon off the back of the 1-0 win against Leeds United in the FA Cup Semi Final wherein McFarlane picked up his first win.
However, the West London side are on a 5 game losing streak in the top flight and could suffer six straight league defeats to nil for the first time ever, ending their hopes of securing Champions League football.
After the sacking of Liam Rosenior last month, McFarlane has steadied the side which he says are easy to coach as he implements some much-needed new ideas.
“I thought the lads performed really well against Leeds at Wembley, which is a really tough opponent. They were in good form with a lot of threats, but I thought we nullified a lot of their threats.
“The players are very coachable. They've obviously had a lot of success recently playing very heavy tactical positional play.
“So they are very open to information and even though they have their own opinions and their own views on the game, they've been a pleasure to work with.
“If there are any adjustments we need to make, they trust and they buy in. We've made a lot of tactical changes in my three games, and they've bought into it. So they're very coachable.”
Forest have not suffered a single league loss at Stamford Bridge since returning to the big time in 2022 but may have their mind on the second leg of their Europa League semi-final next week, where they lead Villa 1-0 on aggregate.
Chelsea have not scored in the past 5 games in the league and McFarlane will aim to get them back on track in what is an early 3pm kick off on Monday afternoon.
