Aston Villa are delighted with Riccardo Calder's progress on-loan with Dundee.
Calder, 19, set up both goals in a 2-1 win over Motherwell on Saturday and has impressed in his past two 90-minute outings.
Dundee boss Paul Hartley said, “Overall he's been good in the time he's been with us.
“He's really positive and he's quick."
