The 18-year-old completed a move to Anfield on Wednesday.
“Danny will handle it,” Weir said. “He has handled everything else that’s been thrown in his path. He’s a good football player and a nice lad.”
He added: “I don’t think it’s rocket science, he just needs to keep doing what he’s been doing. If Danny does go then he will keep doing what he’s doing and stay the same lad that he is.
“He’s a great lad, he has been good to work with, and I wish him every success.”
