The Manchester United takeover process has been blasted as being a "dirty derby" between the two frontrunners by Greenpeace.
British billionaire Sir Jim Ratcliffe is leading one bid for a full takeover, while Qatari banker Sheikh Jassim bin Hamad Al Thani is fronting the other offer. Both groups are holding talks with representatives of the Red Devils, with Ratcliffe flying into Manchester on Friday.
But there are non-football related concerns over both contenders, with Al Thani's bid seen as being closely linked to the Qatari state and Ratcliffe being the founder and owner of chemical giant Ineos. Qatar has faced widespread condemnation over human rights abuses.
