Paul Scholes has expressed his disappointment after Manchester United allowed Danny Welbeck join Arsenal during the summer transfer window.

The England international came up through the ranks of the Red Devils' youth setup and made his way into United's first team. The 20-times English champion's manager Louis van Gaal had made it clear to the 23-year-old that he will not be part of his plan at Old Trafford this season.

Welbeck completed his switch to Old Trafford on the final day of the transfer window. United legend has backed his former teammate to come good for the north London club.

"Naturally, I was sad, as a United fan, to see Welbeck leave this week. My feeling was that if he could have got through this transfer window and stayed at the club he could have been a part of United's future over the next few years," Scholes told the Independent.

"It shows how highly regarded Danny is that a club as big as Arsenal signed him. He will be a good signing for Arsène Wenger. Danny will never be a 20-25 goals-a-season man but he could get Arsenal 10 to 15," he said.

Meanwhile, United allowed another striker Javier Hernandez join Real Madrid on a season-long loan. Van Gaal has signed Radamel Falcao on-loan from Monaco to fill in the void left by the departure of the Mexican international and Welbeck.

The Old Trafford club now have the services of the Colombian international, Dutch star Robin van Persie and club skipper Wayne Rooney as the recognised strikers in the squad. Scholes believes it will be difficult for Van Gaal to accommodate all three in the starting line-up.

"When I watched Radamel Falcao play for Porto, Atletico Madrid and Monaco I saw a striker with excellent movement and a goalscoring record that is simply out of this world," the former United midfielder said.

"At United, on loan for this season initially, Falcao creates competition in United's forward line. There is no way that Louis van Gaal can play Rooney, Robin van Persie and Falcao together. It will have to be two from three and which two it is hard to say as yet," Scholes concluded.
