Conspiracy? Rumours about UEFA not wanting All-english final

The second-leg of the Champions League semi-final between Chelsea FC and FC Barcelona took place on 6 May 2009. Chelsea took the lead from Michael Essien's wondrous strike in the 9th minute. It looked like there would be a repeat of last-year's all-english final when in the last few dying minutes, Barcelona grabbed a precious away goal to send them into the Champions League final. Michael Essien, the initial hero, was to blame. The ball was in Chelsea's penalty box but he cleared it right into the path of Messi, who fed it to Iniesta who then rifled it into the back of the net. That was Barcelona's only shot on target and they made full use of it.
However, Chelsea had four penalty claims turned down by the referee Tom Henning Ovrebo, leading to rumours that he had turned them down so as to avoid an all-english final. Out of the four, at least two were genuine penalties. Although I am not a fan of Chelsea, I feel that it was a little unfair to them.
