The Dons No.1 missed the humiliating 1-0 Scottish Cup loss to sixth tier minnows Darvel last January due to injury.
Dutch stopper Roos was ruled out of the tie with a hamstring tear suffered in the 2-1 Viaplay Cup semi-final loss to Rangers just weeks earlier.
It was an injury that was to sideline the keeper for two months.
Roos couldn’t travel to Darvel with the Dons squad as he had just returned from seeing a specialist in London about his injury.
So he watched it in shock at home on television in the Granite City.
Roos describes that defeat and the aftermath as a “horrible period” and insists those memories are still raw for many at Pittodrie.
Which is why he has vowed they will go all out from the start against League Two Clyde tonight to avoid cup shock lightning striking twice.
