Crystal Palace defender Joachim Andersen enjoyed facing fellow Dane Wiliam Osula and Sheffield United this season.
Andersen played opposite the 20 year-old when Palace won 1-0 against the Blades.
He recalled, "I have spoken to him. He trained a bit with us this summer when we had some training before we went to the real national team gathering.
"I didn't know him there, but I had a chat with him, and we actually have the same agent, so it was a lot of fun. We had a good chat during and after the game, so it was very nice.
"I just told him to keep doing what he's doing. He is a skilled striker who is difficult to play against. He has a lot of power and is fast."
