Arsenal will only consider selling Kolo Toure if manager Arsene Wenger can sign a replacement.

The Daily Mail says Wenger believed he had talked the Ivory Coast international into staying after he handed in a transfer request last month, but it is understood Toure has become disillu­sioned after appearing to fall behind Johan Djourou and Mikael Silvestre in the pecking order at the heart of Arsenal's defence.

Manchester City are set to test Arsenal's resolve with a fresh bid in the region of £10mil­lion for the 27-year-old, who is thought to have fallen out with fellow centre-half William Gallas in recent months.

Wenger had vowed Toure would not leave Arsenal this month but the Frenchman has historically been reluctant to stand in a play­er's way should they express a persistent desire to leave.
