How will Louis van Gaal address his players ahead of tomorrow's big game?
The derby is the first for Louis van Gaal, and he can expect a fantastic atmosphere as these two neighbours go head-to-head once again.
United have not had it good in this fixture in recent years. Last term they were woeful both home and away against their 'noisy neighbours' as David Moyes failed to get his players firing for the fixture.
Van Gaal knows a thing or two about big games with big rivalries. From El Clasico to Ajax v PSV, he has certainly coached some big name fixtures - but no truly massive local derbies other than the Catalan derby.
So he will not know much about the emotions that come with this sort of rivalry - based on proximity, ownership and territory, rather than history and prestige.
So how will he try to serve up the right balance for tomorrow. He wants his players pumped up, but also focused on proceedings. Much of that comes down to the team-talk.
But when asked by Manchester United's official website what type of team-talk he would be giving, Van Gaal gave little away:
“I have to look and analyse what the atmosphere is like. Then I shall say things that are adequate for that moment in my opinion. But the tactical way is always the most important way. We have to play like a team and when we do that we have a bigger chance to win.”
Van Gaal has a reputation for his fiery temper, but so far he has not shown that during his time at United. Once again it will be the cool Van Gaal who takes to the field tomorrow, ready to concisely tell his players what he expects of them, rather than shout it at.
But if they fail to follow those orders, LVG won't be afraid to borrow Fergie's hairdryer.
