It was Giggs who delivered the right-wing cross for Carlos Tevez to nod home his first goal for the club as half-time beckoned.
"You get the ball into the area and hope the centre-forwards get in there," said Giggs.
"Carlos had made a great run - you'll score loads of goals running across the near post and he managed to do that. I was really pleased to see it go in.
"Chelsea have got quality players that can score goals so it was really pleasing to see the second goal go in.
"We're getting players back now so we've got lots of options," Giggs also told manutd.com.
"Nani and Louis were on the bench today so we've got players who can come on and make an impact as well."
