Manchester United manager Ole Gunnar Solskjaer: "I've never felt it [the United job] is too big for me. I'm confident in what we're trying to do and I'm confident in my staff.
"We do have a plan and we know that we've made some decisions that maybe in the short-term would harm us, but we know in the long-term will benefit us.
"But results are always the main thing and we can move forward quicker if we get results and performances."
Liverpool manager Jurgen Klopp: "How much do I enjoy these type of occasions? A lot! It's the salt in the soup!
"They [Manchester United] said it - we are the perfect opponent. I don't think there are too many teams who want to play against us at the moment - it looks like Man United are the only one!"
