St Johnstone striker Gregory Tade is taking a positive attitude into tonight's Europa League second round qualifier.
The Saints take on Turkish club Eskisehirspor in the second leg at McDiarmid Park following their 2-0 loss last week but Frenchman Tade, who missed that match due to injury, believes the deficit can be overturned.
Tade feels that Barcelona's efforts in the Champions League last season, when they were beaten by Chelsea, suggests to him that this fixture is not out of reach for St Johnstone.
"I am always positive. There's no defence in the world that cannot be cracked," he said.
"Barcelona are the best team in the world, but they still didn't win the Champions League or La Liga.
"Lionel Messi is the best player in the world, but he missed a penalty at a crucial time against Chelsea. In football anything can happen.
"I'm sure Eskisehirspor have conceded goals before and we will have a go to make that happen here.
"We have belief because if you don't believe you would be as well staying at home.
"I have learned in Scotland that you always have to have confidence in yourself."
