Manchester City are continuing their pursuit of experienced performers for their intended assault on the Premier League this season.
Over the last two transfer windows Mark Hughes has been particularly determined not to create a team of 'galacticos', but the inevitable pressure on him to deliver as soon as possible has brought forward his squad developments by at least six months.
City are therefore willing to pay a premium to get quality, proven Premier League players to position themselves as a real force.
City have been looking to sign Toure since January and it seems a bid of £15m has convinced Arsenal and Toure to make the move happen.
The transfer is likely to add pressure to Wenger and relieve some from Hughes who can almost boast of squad ready to challenge most others teams.
Questions will no doubt be asked of Wenger who is apparently comfortable weakening his own squad whilst strengthening that of their likely challengers for a Champions League spot.
