David Weir has urged Rangers not to dwell on the defeat at Hearts which knocked them off top spot in the Scottish Premier League on Saturday.
The veteran defender insists the Ibrox club must forget the Tynecastle match and look ahead to Wednesday's Champions League match against Stuttgart.
Rangers have been drawn in the so-called "group of death" with Lyon and Barcelona, as well as the German champions, and know victory in their opening match is essential before facing the Group E heavyweights.
Saturday's 4-2 mauling was hardly the ideal preparation but Weir said: "We need to get back playing, address it, and put the wrongs right. The game is gone. There are a lot of things we would like to change if we could but we can't. We've got to look to the future now."
Celtic manager Gordon Strachan admits his side's 5-0 demolition of Inverness Caledonian Thistle at Parkhead allowed him to give some respite to key players for tomorrow's Champions League clash with Shakhtar Donetsk in Ukraine.
The champions leap-frogged Rangers for the first time this season with two goals from Jan Vennegoor of Hesselink and one each from Massimo Donati and Shunsuke Nakamura, with a Phil McGuire own goal compounding the visitors' misery.
Dundee United moved into third place yesterday with a 2-0 win over St Mirren at Tannadice Park.Reuse content
