Raul’s former Real Madrid team-mate Figo says the veteran forward is in the kind of form which can dump Sir Alex Ferguson’s men out of Europe.
“They are not the best team in terms of quality but they have the ability to surprise you.
“They are well-organised, they play like a team, and they have Raul, who is very experienced.
“Raul is still playing at a high level and it doesn’t surprise me because he’s a great professional. He always has been.
“I am happy that he is doing well in the Champions League and the Bundesliga. United’s defence will have to be careful of him.
“Schalke will be highly motivated to reach the final, and the confidence of beating Inter Milan in the last round mixed with that means they can surprise everyone.”
