Wilfried Zaha is the latest in the long line of players who will be making the big step-up into the Premier League. For teams, managers and players, the Premier League has often proven to be a completely different animal to the football league.
Some come in and adapt immediately. But not many. Some take time, but eventually prove they are Premier League class. Most players struggle to make any real impact.
There will be a lot of pressure on Zaha to make an impression at United. Alex Ferguson demands a lot from his young players. The likes of Phil Jones, Javier Hernandez and Chris Smalling will testify to that, as they were thrown straight into the first team after signing for the club.
For the time being, Zaha will remain at Crystal Palace. But when he joins the United squad next summer, you can bet that Ferguson will have every intention of utilising him in the first team. It is very much a "sink or swim" approach at United for the younger players.
With that in mind, I looked back to players that the youngster might look to emulate. Players who have come into the Premier League from the lower divisions and have made a real impact for their respective clubs.
