Giggs scored his 150th goal for the club and equalised Edin Dzeko’s shock opener.
Ferguson told ITV: “He’s unbelievable. With all the superlatives and praise he’s had over the years, I don’t know how you can add to it. He’s a marvellous player.”
Ferguson added: “Their goal was a surprise but I thought it was a matter of time before we scored. We got a bit fortuitous for our goal with the deflection but the performance deserved it.
“I thought it was a very good performance. What they are good at is they never give in. No matter what the score is, they keep playing and they get their reward. Our performance level was very good.”
