The 41-year-old told reporters: "He is a very decisive player - an amazing player because of his speed, strength and goalscoring abilities.
"He has shown that throughout the season this year so I rate him very highly.
"Our collective game needs to be very strong tomorrow. We can't just focus on Gareth Bale - there are other players in that team that can raise their game."
