Walter Smith yesterday lambasted both the Scottish Premier League and Peter Lawwell, the Celtic chief executive, over the rescheduling of the final league games of the season, which may force Rangers to play four games in eight days.

While Smith criticised the SPL’s recent decision over the fixtures as “unfair”, he openly lampooned Lawwell for his much-quoted “sporting integrity” statement, in which the chief executive argued against extending the season in order to help Rangers to fulfil all their remaining matches.

If Rangers do not reach the Uefa Cup final, the SPL has still decreed that no outstanding games should be played in the free week between May 18, when the Clydesdale Bank Premier League is due to finish, and May 24, the day of the Scottish Cup final.

“Why could we not have played a game in that week? What the SPL has done, instead, is force us to play four games in a week,” Smith said yesterday. “Is it right to force a club to do that? I don’t think it is, regardless of which club it is. From Rangers’ point of view, the league have opted out of making a decision which would have helped a club which is helping to lift the profile of Scottish football [in the Uefa Cup].

“We then have this ‘sporting integrity’ situation, which actually gave me a good laugh. Peter Lawwell seems to be the head of the sporting integrity committee — both its chairman and chief spokesman. Peter would be better coming out and saying he wants Rangers to have to play four games in a week because it suits his team and helps their quest to retain the championship — he should just be honest about it.

“If it was the other way about, I would be hoping that Celtic had to play four games in a week, so fine. But Peter is as well being honest about it, instead of hiding behind what he is calling ‘sporting integrity’.”

Smith appeared to hint heavily that he believed the SPL had been overly-influenced, if not simply manipulated, by Celtic in their revision of the fixture list.

“What bothers me most is that the SPL have assented to every request that has been made by Celtic, especially these two [Old FIrm] games that we’ve had at the moment,” Smith added. “It is no coincidence that we are playing one of our biggest league games of the season when they had a fair idea that we would have two very important {Uefa Cup] semi-finals.”
