Celtic keeper Fraser Forster expects a tough test when his side travel to Inverness on Saturday, but is confident of progression.
The Parkhead club have already managed to reach the League Cup final and Fortser is eager for Celtic to continue their quest for silverware in the Scottish Cup.
However, the on-loan goalkeeper expects a tough tie at the Caledonian Stadium, but remains confident Celtic can secure the win.
"The pitch won't be great, and they are always fired up when we go there," he told Celtic TV.
"It'll probably be windy and all the conditions will be against us.
"
But it's one of those games where we have to go and play the way we can because we just want to stay in another competition."
Forster is on a season long loan deal at Celtic, but is expected to complete a permanent £2million move from Newcastle in the summer.
