Arsenal face fresh competition from Manchester United in the race to sign Gary Cahill, according to reports.
The England international has been courted by a number of Barclays Premier League clubs in the last 12 months, with Arsenal boss Arsene Wenger the most heavily linked with a move for the player.
Fresh reports in the Daily Telegraph now claim Manchester United have intensified their chase for the Bolton Wanderers defender, with Sir Alex Ferguson dispatching scouts to track the player's progress.
Valued at £25 million by Owen Coyle in January, the figure was thought to be a major stumbling block in a potential Arsenal move with the Frenchman desperate to bring a centre back to the Emirates.
A move for Cahill, or any defender, failed to materialise for Arsenal though, and Cahill has continued to build on his impressive reputation at the Reebok Stadium.
Manchester United are now in the market for a defender following continued injury concerns for defender Rio Ferdinand, with Ferguson keen to strengthen the Red Devils in the potential problem position.
The Trotters are bracing themselves for bids in the summer, and both Arsenal and Manchester United are expected to come to the table at some point with an offer for the England international.
Chelsea are also thought to be keen on landing the player, with the west London outfit also interested in the 25-year-old former Aston Villa defender.
Arsenal are still thought to be favourites though, although the Gunners will have to fight hard to see off Manchester United if these claims are to be believed.
