Two Brazilian congressmen have called for an investigation to establish whether the deal was a way for Ms Precht to return to Mr Teixeira some of the money Ailanto earned from the Brazil-Portugal friendly.
Six months before the match Sandro Rosell, who is now the president of Barcelona Football Club, the European champions, became a director of Ailanto, a sports-marketing firm in Rio de Janeiro set up shortly beforehand.
One dated March 2009 commits Vanessa Precht, a Brazilian who formerly worked at Barcelona FC and who was Mr Rosell's partner in Ailanto, to leasing a farm in the state of Rio de Janeiro from Mr Teixeira for 10, 000 reais a month for five years.
