The two homegrown talents are hoping to represent England in the World Cup finals and are determined to prove their worth at domestic level ahead of this summer's showpiece tournament in Brazil.
Welbeck came off the bench against West Brom on Saturday to display a cool head in front of goal, stroking in the third goal at The Hawthorns when Jonas Olsson was unable to cut out Wayne Rooney's through ball.
"Wayne played him in with a great pass before then but it was a bit of a narrow angle and the pitch was really lively," explained Moyes to MUTV. "When he was played in down the side, he opened up and finished terrifically well. I'm pleased Danny is looking sharper and getting back ready. We're going to need him."
Cleverley was not involved in the 3-0 triumph on Saturday with the boss explaining the thinking behind the decision.
"I just felt he wasn't required today," he stated. "I wanted to make sure Darren Fletcher and Ryan Giggs were involved. We've got a lot of big games coming up and Tom will be involved in a lot of these in the coming weeks."
