Sheffield Wednesday head coach Carlos Carvalhal has claimed that his side have a minimal "10% chance" of knocking Arsenal out of the Capital One Cup on Tuesday.
The Championship outfit, who are on an unbeaten eight-game run, will host the two-time winners at Hillsborough in the fourth round.
"We will fight for the whole match and we will be competitive," Carvalhal told BBC Radio Sheffield. "It will be interesting to see how it goes.
"We have probably a 10% chance of getting through. It is not very much but it is better than zero. Zero means you can do nothing, 10% means we will have 10% of the chances and we have to grab them."
Wednesday last defeated Arsenal in September 1998.
