Manchester United hero Norman Whiteside sees manager Sir Alex Ferguson overhauling his squad this summer.
Whiteside believes Ferguson has started to replace some of the older faces in the Man United squad.
He told talkSPORT: "He's got Smalling and he's got Phil Jones.
"They both played very well for England Under-21s, so he's [Sir Alex Ferguson] not just looking for next season he's building for the future.
"I can see another few players coming in as well and trying to safeguard the Premier League for next year, they'll be going for number 20."
