Midfielder Claudio Yacob, who was free of Racing, regretted having signed a preliminary contract with English club West Bromwich Albion and now want to break that agreement to go play Botafogo, Brazil, as published on Thursday the Brazilian press.
Yacob, according to Globo Esporte, repented of the firm because in the pre-contract accepted a certain salary in England unaware that taxes are too high.
Botafogo offers $ 125,000 salary, double what they earn in England, and that is why Yacob communicated with club leaders and asked them, crying, according to that average, wait until you cancel the signed document with West Bromwich.
The Argentine now needs to convince the British to cancel the pre-contract and quickly move to Brazil, because tomorrow closes the book of passes in the South American country.
Yacob was U-20 world champion with the Argentine national team in Canada 2007 and was free of Racing last month, without having played in the past six months to be separated from the upper campus not to renew his relationship with the entity of Avellaneda.
