Tottenham are reportedly leading the hunt for highly-rated Crystal Palace youngster Wilfried Zaha, with Arsenal, Liverpool, Manchester City and Manchester United all pursuing his signature.
According to the Daily Mail, Manchester United have joined the list of clubs chasing the 19-year-old, while Arsene Wenger sent chief Arsenal scout Steve Rowley to watch Zaha in action last week.
Andre Villas-Boas, however, is reported to be in pole position to bring Zaha to White Hart Lane ahead of Spurs' Premier League rivals, although Crystal Palace maintain it would take £20 million to land the winger.
Where a bidding war to ensue for Zaha, then Manchester City would surely be favourites to sign the England under-21 international, given their vast resources at Roberto Mancini's renewed focus of bringing young talent to the Etihad Stadium.
Arsenal, meanwhile, would have to break their transfer record if Gunners boss Wenger is serious about signing Zaha, while £20 million may be an outlay too far for Liverpool given their wasteful spending in recent times.
Liverpool owners Fenway Sports Group, however, have shown a willingness to concentrate on youth recruitment, so may provide Brendan Rodgers with the tools to sign Zaha, should the Reds boss want to bring him to Anfield.
At Manchester United, meanwhile, the possible exit of winger Luis Nani could potentially lead to a move from Zaha, although Sir Alex Ferguson has been linked more frequently with Porto's James Rodriguez.
