"I think he [Bale] has been unbelievable," Gibson told evertontv. "He's won games for Spurs on his own.
"It's good for English football and it's good for Spurs but hopefully he is not good on Sunday against us. I think he is up there with the best in Europe at the minute.
"Seamus has dealt with him quite well the last two times he has played against him.
"He's a great player and I don't think there is one particular way of stopping him. We're good as a team defensively and we work hard for each other, so hopefully we will be alright."
