Raulâ€™s former Real Madrid team-mate Figo says the veteran forward is in the kind of form which can dump Sir Alex Fergusonâ€™s men out of Europe.
â€śThey are not the best team in terms of quality but they have the ability to surprise you.
â€śThey are well-organised, they play like a team, and they have Raul, who is very experienced.
â€śRaul is still playing at a high level and it doesnâ€™t surprise me because heâ€™s a great professional. He always has been.
â€śI am happy that he is doing well in the Champions League and the Bundesliga. Unitedâ€™s defence will have to be careful of him.
â€śSchalke 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.â€ť
