Rangers sent firm Aberdeen warning as former Ibrox star tells Steven Gerrard that Celtic showing won't cut it

dailyrecord.co.uk:

Rangers didn’t have to be at their best to win last month’s Old Firm derby at Parkhead.But Richard Foster reckons they must find top gear ahead of the biggest test of their new-found winning mentality against Aberdeen on Sunday.Foster, who had spells with the two rivals, knows the Light Blues are a different animal this season but believes we’ll find out just how ruthless they are when Derek McInnes takes his Dons to Ibrox.Rangers have already overcome bogey team Kilmarnock twice in the Premiership this term to show they have learned from costly slip-ups against the Ayrshiremen.And, having won at Pittodrie on the opening day, Gerrard’s men now have the chance to do the same against a Dons side who have inflicted damage on their silverware.
