With Manchester United's transfer activities making new headlines there has been much debate over exactly how many signings the squad needs to challenge for the title next year, with Scholes' former teammate Gary Neville suggesting that three signings could be enough.
Scholes however, is not as optimistic about the strength of their current squad, claiming that the club needs an investment of similar proportions to last year's spending, when they made five major additions to the first-team squad including Ander Herrea, Daley Blind, Marcos Rojo, Angel Di Maria and Luke Shaw, along with bringing in Radamel Falcao on loan.
Scholes thinks a similar investment, which totalled to about £150 milion last summer, will be needed to make the Red Devils title contenders once again.
Speaking to Sky Sports, Scholes said: "I think United will be looking for maybe a centre-back, a right-back, possibly another goalkeeper, a top class centre-forward, and even maybe a wide player so that is five players.
"We have seen them in the big games against the big teams and they have not been far away, they have probably played better against the big teams.
"They have a way to make up with Chelsea and Manchester City. Arsenal don’t worry me as much. But there is quite a gap between them top two and it’s a gap they will have to have to bridge.”
It seems the club's first major signing this summer will address their need for a wide player, Memphis Depay was scheduled to fly into Manchester on Monday to complete his medical with the Red Devils.
De Gea's future
However Scholes feels the uncertainty regarding David De Gea's future is the biggest problem faced by United at the moment.
There is growing concern that goalkeeper De Gea, who only has a year left on his contract, will make a return to Spain after drawing attention from Real Madrid as a result of his impressive performances throughout the season.
"What is coming out of the club is a little bit worrying to be honest with you," said Scholes.
"But can you blame him? He’s a Spanish lad and if Real Madrid want him then they normally get someone, and they have every chance of getting him.”
De Gea was chosen by his team-mates as the Manchester United Players' Player of the Year on Tuesday and United would have to search very hard to find a suitable replacement for the Spanish stopper.
United fans, what do you think are United's main priorities this summer?
