After loaning both players to Championship teams last year, Welbeck to Preston and Cleverley to Watford, Ferguson believes the time is right for the pair to be tested in the top flight.
With limited opportunities for the England Under-21 internationals to make any impression on the first team at Old Trafford, the Scot is ready to send them on seasonlong loan deals, with the North-East rivals leading the chase for their services.
Sunderland have made public their desire to add Welbeck to their contingent of Man United old boys that includes Fraizer Campbell, Phil Bardsley and manager Steve Bruce.
Welbeck is regarded as a hot prospect at Old Trafford, but Ferguson wants the youngster to benefit from playing on a regular basis and talks have already begun over a proposed loan switch to the Stadium of Light.
This is going to be a big season for Danny because for the last three years he has not had a consistent run of games. I sent him to Preston as you know last year, said Ferguson. He got an injury almost right away He only played five games and ended up having an operation on his knee.
One of the things about Danny that may have caused the injury is that he is still growing. He has a weakness in his legs with the speed he is growing.
He is about 6ft 2ins and a bit now. He has sprouted up in the last year and a half.
So, he needs consistent football. He needs to play all the time and that is one of the reasons we are considering sending him on loan again to a Premier division team.'' Newcastle have enquired about the availability of midfielder Cleverley who despite suffering knee ligament damage in April, was named Watford's player of the year.
With limited funds available for squad strengthening Cleverley's ability to operate in several positions adds to his appeal for the Magpies who would face competition from Bolton and Fulham.
Ferguson said: Tom is a very talented boy. He is going to be a very good footballer.
We are also considering putting him on loan to a Premier division team.
He improved tremendously in his spell at Watford last year. He has just come back (from injury) and can play anywhere in midfield, which is always an advantage.
