Millwall represent the latest threat to the Owls’ recent run of resistance and Stuart Gray insists his side must be on their guard at The Den on Tuesday night.
The newly-appointed head coach has engineered a significant revival since taking the S6 reins, leading Wednesday to eight unbeaten games in league and cup competition.
But Gray – having seen his own impact in the hot seat – is acutely aware of the upside of changing the manager.
The Lions are led by Ian Holloway, who was unveiled as Millwall chief earlier this month.
Gray said: “Millwall were unlucky not to get a point at Huddersfield then won their first game at home under Ian so it seems he has had an impact at the football club in the short time he has been there.
“Everyone knows his record in the game, he is an excellent manager and I’m sure there will be a feelgood factor around the place.
“But we will be concentrating on our own positives because we go there with confidence and we know we are capable of getting a result.
“This is a huge week for us with two games against teams in and around us in Millwall and Barnsley.”
The Owls head to the capital minus the services of Connor Wickham – recalled by parent club Sunderland on Monday – in addition to an over-populated treatment room.
But Gray believes that situation merely opens the door for others to impress.
He said: “Obviously it’s a blow losing Connor because he has done so well for us but as one door closes another one opens and someone else has to make a case for taking the shirt.
“It’s the same with the injured players – someone else can come in and make the shirt their own.
“So that is an upside in itself because we have players who have done that and when the injured lads come back, it will be like new signings with the quality they have and competition they will bring.”
