Liverpool great Graeme Souness insists Raphael Varane and Jadon Sancho won't be enough for Manchester United.
United finished second last season, but champions Manchester City have added £100m Jack Grealish and will look to spend even more on Harry Kane to lead their attack, while Chelsea are set to re-sign Romelu Lukaku for £97m.
“If Manchester United have finished their transfer business with the signings of Jadon Sancho for £73 million from Borussia Dortmund and Raphaël Varane for an initial £34 million from Real Madrid, then that is not enough investment for them to win the trophies this season that a club of their magnitude should be aiming for: the Premier League and Champions League," Souness wrote in The Sunday Times.
“The signing required to catapult them into title-winning contention with Manchester City and Chelsea is a striker who guarantees 30 goals a season.
“There are few of them around and you will pay a premium if you are a Premier League club and another premium on top of that if you are one of the big boys."
