Man Utd 'agree personal terms' with Alex Telles as Ed Woodward looks to strike Porto deal
Manager Ole Gunnar Solskjaer discussed the prospects of bringing in further new players at his pre-match press conference on Friday.
"Of course, we've done some business with Donny, I'm very happy and delighted to get him in," Solskjaer said.
"An exceptional, smashing lad that'll give us something. I can't say anything about other clubs' players out of respect for them, I can't speculate.
"We understand that to get even further, one, we need to develop what we have and, two, we need strengthen the team.
