Nemanja Vidic says the Reds will learn valuable lessons from Saturday’s 4-3 win over Hull City.
United claimed all three points but the visitors became the first side to score three times at Old Trafford in 92 games (Chelsea beat United 3-1 in May 2005).
Ronaldo might be benched against Celtic as Carlos Tevez and Anderson are back in contention after missing Saturday's 4-0 win over West Bromwich Albion.
Paul Scholes, Owen Hargreaves and Michael Carrick miss out of course and they are joined in the stands by Patrice Evra who was taken off with a hamstring injury against West Brom and won't be risked tomorrow night.
A brand new website has been launched that lets you send messages to the top players, like Carlos Tevez, Michael Carrick or Rio Ferdinand, and get guaranteed responses!
Around 100 Premiership footballers have signed up to use www.contacttheplayers.com to respond to fanmail - and they get back to you within a week!
The first message is FREE, and after that its just a quid per message!
ONE day he will be a regular Manchester United centre-half". That's the view of Manchester United manager Sir Alex Ferguson on Newtownabbey lad Jonny Evans.

Manchester United failed to become the ninth British winners of the Uefa Super Cup when they lost narrowly 2-1 to an impressive Zenit St Petersburg in Monaco.
For the first 60 minutes Zenit were comfortably two goals ahead through a fist half header from Pogrebnyak then a wonderful solo effort from Portuguese star Danny on 58 minutes.
Sir Alex has taken a 19-man squad to Monaco for Friday night’s Super Cup clash with Zenit St Petersburg.
The Reds left Manchester Airport on Thursday morning at 09:00 BST and will train at Stade de Louis II later in the day. Kick-off on Friday night is at 19:45 BST.
Manchester United defender Nemanja Vidic claims to have been misquoted in an interview with Russian football magazine Football Weekly in which he was critical of the Manchester weather and the English lifestyle.
Complaining about the weather is one of Britain's most treasured hobbies, so Sir Alex Ferguson must be unsure whether to praise Nemanja Vidic's integration into local culture or to criticise his lack of diplomatic skills after the Serbian defender spoke about his rain-induced depression yesterday.
