The Sunday Mirror says chief scout Steve Rowley watched the Bolton Wanderers centre-back in action against QPR will surely tell his boss that Cahill is made for the Gunners.
In fact, the goal Cahill despatched to set Bolton on their biggest away win for six years was good enough to grace the Emirates or any other home of Champions League football. Arsenal are well aware there's a get-out clause in Cahill's current contract which values him at around £16.5 million.
Cash-rich from the impending departures of Cesc Fabregas and Samir Nasri, a move for Cahill makes absolute sense.
Wenger has been searching for a new central defender for months. Cahill is the clear favourite and has moved ahead of Blackburn's Chris Samba.
