Securing the superstars of tomorrow is a chief concern for Manchester United following reports the Premier League giants are in the hunt to sign Paris Saint-Germain's Marco Verratti and Milan starlet Gianluigi Donnarumma.

United have been put on alert after learning just how much Verratti's signature could set them back. His agent, Donato Di Campli, told France Football the Italian is "worth as much" as Paul Pogba, who has been valued at €100 million (£72 million) in the past (h/t James Cambridge of the Daily Express): "If Kevin De Bruyne signs for Manchester City for €80 million, then €100 million for Marco does not seem unreasonable. I hear here and there that Pogba is €100m. For me, Verratti is worth as much."

Verratti turns 23 in early November and has made a meteoric rise through the ranks at the Parc des Princes since arriving from Pescara in 2012, already racking up 143 appearances for the Ligue 1 outfit.

Despite his age, Verratti has come to be recognised as one of the biggest talents in the French top flight, and WhoScored.com recently pointed out his elite value as a passing master among Laurent Blanc's squad:

The centre of Manchester United's midfield has been significantly reinforced by the signings of Ander Herrera, Bastian Schweinsteiger, Morgan Schneiderlin and Daley Blind over the past 18 months.

However, one could understand why manager Louis van Gaal may have one eye fixed on the future as Schweinsteiger, 31, and Michael Carrick, 34, creep further toward the end of their peak performance, if not past it already.

Cambridge's report mentions that Verratti was open to leaving Paris over the summer, but PSG prevented their valued asset from departing. But the dynamic there between the two parties may only be maintained for so long.

Spanish football writer Sergi Dominguez goes further than Di Campli and professed that Verratti is even superior to Juventus superstar Pogba:

Of course, Verratti's agent is as likely as anyone to hype up the transfer value of his client, but United could choose to flex their financial muscle in 2016 should they feel £72 million is a fair sum.

Any chances of signing Verratti look slim, and the same could be said for Milan goalkeeper Donnarumma, who will reject any offers of a transfer as he looks to tie down his future with the Rossoneri.

According to Italian outlet Calciomercato (h/t Charles Perrin of the Daily Express), the 16-year-old being dubbed "the next Gianluigi Buffon" will spurn any outside interest.

Donnarumma etched his name in Serie A history on Saturday after starting in goal for Sinisa Mihajlovic's side in their 2-1 win over Sassuolo, per Bleacher Report UK:

The 6'4" teenager conceded a difficult free-kick to compatriot Domenico Berardi, but he was, for the most part, impressive as he made his league debut for the Italian powerhouse.

Mihajlovic made the decision to drop former Real Madrid stopper Diego Lopez in favour of Donnarumma based solely on talent alone, he told the press after Saturday's win, per Football Italia:

I chose Donnarumma because he has great technical and physical qualities, he’s better than Diego Lopez right now. I haven’t taken off Lopez because he conceded a goal in Turin, but because at the moment I see Donnarumma as better. They are two great goalkeepers with great personality and who are very reliable.

United's goalkeeper woes are over for the time being after David De Gea remained at the club this season following a summer of exit speculation, not to mention recently penning a four-year contract extension.

Mihajlovic's review suggests there will be more Serie A experience to come for the starlet, and it seems Milan can rest easy knowing Donnarumma has full intentions to be a success for the Rossoneri.
