Arsenal are reportedly ready to battle it out with Premier League rivals Manchester United for the signature of Porto midfielder Vitinha this summer.
The Gunners are targeting a midfielder and could be ready to trigger the Portugal international's £34million release clause.
The 22-year-old has already been attracting interest from some of Europe's elite clubs including United and LaLiga giants Barcelona.
Arsenal have now joined the race and look set to make a move for the youngster this summer, according to Portuguese newspaper Record.
