Former Celtic striker Scott McDonald knows a thing or two about the Hoops making progression in Europe.
He was part of the Celtic squad which made the last 16 of the Champions League in 2008.
He firmly believes that the current side Celtic can also make progress in Europe, and reach the latter stages of the Europa League.
“The football they’ve been playing is phenomenal” McDonald said, as reported by BBC Sport. “They’ve still got Rennes to come to Celtic Park, so I’m more than confident they will reach the next stage.”
