Manchester United manager David Moyes does not have any experience in the Champions League proper.
His only previous experience of the competition was in the 2005/06 campaign when Everton failed to qualify for the group stages of the Champions League against Villarreal.
Moyes has admitted to watching Champions League football at Old Trafford and Celtic Park but he hasn't had a first-hand experience of what it takes to help a team like Manchester United progress to the later stages of the competition.
That is why Manchester United's Ryan Giggs will play a pivotal role in Moyes' inaugural Champions League campaign.
The United player/coach has one of the highest appearance records in the Champions League.
He has been involved in the highs of a Champions League final win on two occasions and has lost participated in two finals against Barcelona when the Red Devils were rightly beaten by the La Liga giants.
That is why Moyes pulled off a masterstroke by appointing the 39-year-old onto his coaching staff.
Moyes' assistant manager Steve Round, first-team coach Jimmy Lumsden and goalkeeping coach Chris Woods are all in the same boat as the 50-year-old manager.
Phil Neville will also be a valuable aide to Moyes, as he also knows what it takes to win the competition - having playing in the run up to United's Champions League triumph in 1999.
Moyes will also seek advice from Giggs' fellow senior stars such as Rio Ferdinand, Patrice Evra and Nemanja Vidic.
Ferdinand said back in July that Manchester United's old guard would be there for Moyes if he needed someone to 'lean on'.
The 34-year-old said: "I just look at it as if I was taking the job on. Would you lean on players who have been here for many years? Of course you would.
"I think the manager is fortunate he’s got someone like Giggsy, among others like myself and Carras (Michael Carrick), who know the fabric of the club.
"If there’s anything we can pass on to help him become a better manager and to help us win more trophies, that’s fantastic."
Ferdinand and co will provide United with the valuable knowledge of the Champions League on the pitch but it is Giggs who will be the perfect person to lean on if Manchester United are struggling in the prestigious competition.
