"I was involved in it last year," Whiteside told ManUtd.com. "I went down with Lou Macari and had a lovely day. So many people turned up and the weather was great.
"I met loads of people and I'm on Twitter a lot so every single person Tweeted me afterwards saying what a great day they had and how well looked after they were.
"I think, first and foremost, it's a privilege just to get through the gates at Carrington! The facilities are excellent - some of the boys last year couldn't believe it as nobody gets that close to it. It's completely different to Old Trafford, that's a one-off match situation and the players only play there about 20 days a year.
"They train every day at Carrington and the facilities are all absolutely spot-on. The pitches are immaculate and it's a chance to come and enjoy it and see where the team comes every day. It's their place of work, if you like."
