Plymouth have completed the signing of young Manchester United defender Craig Cathcart on a six-month loan deal.Sturrock is delighted with the signing and says he will add quality to the Pilgrims squad.
"Craig is a big centre-half that we have been watching from afar," said Sturrock. "He is a good centre-half with good qualities and you don't play for Manchester United if you're not of a very decent standard.
"I'm very happy to bring the boy on board and it is up to him to get himself in the team."
