Wolves are seeking legal action over Arsenal's deal to sign Brazilian teenager Marquinhos from Sao Paulo.
The Gunners are believed to have agreed a £2.5million transfer with the Brazilian outfit and a transfer is expected to be announced in the coming days. The 19-year-old is said to have agreed a contract at Arsenal and travelled to London to complete a medical.
Marquinhos, who can play down the middle or on the wing, is one of the most highly-rated youngsters in Brazilian football. He's represented his country at youth level and played 41 senior games for Sao Paulo, scoring four goals and providing three assists.
