Former Porto presidential candidate Nuno Lobo has criticised the club for the imminent sale of Fabio Vieira.

Arsenal are set to secure the signing of the midfielder for a fee of around £34million.

Speaking to Bola Branca, Lobo said: "He is one of the best players at FC Porto and leaving for this fee is a bad deal.

"We are talking about one of the gems of FC Porto, one of the players who came from our academy. The DNA of FC Porto.

"We lost him. It's another piece of business that I don't understand.

"We are talking about ridiculous values for players who represent and are FC Porto.

"They are from our academy and we are letting them go for unbelievable fees."
