The Blues boss made the claim after dumping Manchester United out of the FA Cup last week.
But Wilkins told Absolute Radio: "No, I am inclined to disagree with Rafa but I did that in the week and got slightly punished by it. We are all entitled to our own opinion. So I don't think they had an opportunity within the world club championship, which they failed, had a fantastic opportunity of taking the Capital One Cup, but lost in the two legged game against Swansea. And it's a fight now; it's a fight now for the top four. Tottenham without Bale, both Arsenal and Chelsea an amazing advantage over the next couple of weeks to push themselves a bit closer to that third and fourth place.
"So no, I wouldn't say it's a fantastic season for Chelsea at all. Yes they can possibly win a couple of cups but at the end of the day Chelsea is more than a Team now, Chelsea is about winning championships and they haven't been competitive as far as the championship is concerned."
