The 38 year old former Manchester United defender and English international thinks that the Red devils should go for Bale and Greizmann in the next transfer season.
The former stopper of Manchester United thinks if the club has that amount of money with them they should go for them.
In the beginning of the 2016-2017 season the Manchester United side signed the French midfielder Pogba from Juventus with a record breaking fee.
Also last season they signed the young Ivorian professional footballer Eric Bertrand Bailly from Villarreal with a sizeable fee, and also the Swedish striker Zlatan Ibrahimovic gets an attractive package from the Manchester United side, and also they brought Henrikh Mkhitaryan from Borussia Dortmund.
There are rumors regarding Greizmann that he will make his move to the Old Trafford in the next season.
Also Manchester United will go for real Madrid star man Bale and they are after him since he was with Tottenham.
To sign them Manchester United have to break their bank accounts, but the former Manchester United defender believes that Manchester United have that money in their pocket to bucket those players from the Spanish league.
Rio Ferdinand said that: "Manchester United have got the money, I’d go get both.
"They’re great players but I don’t think they’re comparable to be honest. They’re different players.
"Gareth could play anywhere across the front-line. He’d be effective anywhere – from the right to the left, central.
"Griezmann obviously [would play] as the number nine, but right now might be too early. Ibrahimovic is banging in goals.
"If they became available, Manchester United have to be in that."
But the Manchester United manager Mourinho is searching a defensive player rather than an attacking player they his search will be on till the next transfer season.
