United host the Blades tonight at Old Trafford.
Solskjaer said: "They've had a fantastic season. I don't normally like to speak too much about the opposition, but you've got to give praise where it's due. They've had a few promotions now, and Chris has done a fantastic job with his players and with the club.
"And for us, with Dean Henderson having been there, he's really stepped up and done well for them, so I'm very happy with what he's helped us with, but also happy for Chris with his local team. He's such a big Sheff United fan, so you know what it means to him."
He added: "(We're) looking forward now to Sheffield United, welcoming Ollie Norwood – another one of our boys who's done exceptionally well, [and we're] pleased and proud to see him and the career he's had. But let's make sure he's not going to enjoy coming back."
