Manchester United assistant manager Ryan Giggs has urged the club's youngsters to seize their chance to impress boss Louis van Gaal.
The Dutchman has promised to give a number of the junior players opportunities on the pre-season tour to the United States as he is keen to re-establish the production line from the academy to the first team.
And Giggs, who is one of the most famous examples of that progression, has some words of advice for those travelling to America.
"Young players might come on tour thinking they'll not get many minutes but then suddenly there'll be an injury to a senior player," he told manutd.com
"The young player might then have a 10 or 15-minute cameo, play really well, get into the team for the next game and do really well again.
"So the tour is definitely an important stage for the young players to make their mark.
"I think you've seen a lot of players play well in pre-season and take that into the first part of the season.
"It's a massive thing as an individual to get the best out of yourself.
"If you can get off to a good start it gives you confidence so you definitely can't take the pre-season games lightly.
"Gone are the days when you'd play easy games - every match is tough."
Meanwhile, United striker Javier Hernandez was taken to hospital after suffering an injury while playing for Mexico against Honduras in a Gold Cup warm-up match on Wednesday night.
According to reports, the 27-year-old has suffered a broken collarbone, although the Mexican Football Federation has yet to confirm the nature of the injury. "We have no report, all I know is that he has gone to hospital," coach Miguel Herrera said on the federation's website. "We have not yet seen the results.
"It will have an impact on the group but we're just thinking about what is ahead."
