Tang En had only just set foot into the UK when negotiations between Nottingham Forest Club and FC Porto regarding Pepe's transfer began. The other relevant issues in relation to the matter proceeded as well.
Other than the negotiation between the two clubs, there was another matter that could not be ignored: Pepe's work permit. Although Pepe has been playing football in Spain for numerous years, he held only Brazilian citizenship and was thus considered a non-EU player. As he was never fielded as a representative of the Brazilian National Team, he could not fulfill the 75% participation rate in senior international matches. If the transfer got blocked because of the work permit issue despite all three parties (the two clubs and the player himself) not having any problems with it, Tang En would be enraged. He had not had such problems when he was playing FM.
