Manchester United hero Arthur Albiston has no doubt fans will get behind their new signings.
Albiston told ManUtd.com: "Our supporters are renowned for giving people time. Of course, there's nothing they like more than watching young players come through the United ranks into the first team but they'll have similar feelings about Jones and de Gea, given they're only 19 and 20.
"The fans at Old Trafford have loads of patience with new players coming to the club, especially young ones, and they'll get behind them.
"Everyone's going to make the odd mistake but our fans are very forgiving. I'm sure Peter Schmeichel would hold his hand up to one or two mistakes in his first season. That's something that goes with the territory.
"The crowd will give de Gea, Jones and Young every backing and if the new boys perform as well as Javier Hernandez and Chris Smalling did in their first season, I'm sure the supporters and the manager will all be delighted."
