Arsenal's pursuit of defensive reinforcements has led them to Chelsea centre-back Alex, it has been claimed.
According to The Sun, the north London club are keen on the 29-year-old Brazilian, who is valued by his current employers at around £10 million.
Alex was an unused subsitute for Chelsea during Saturday's 3-1 win over Norwich at Stamford Bridge, with John Terry and Branislav Ivanovic preferred in the centre of defence by Andre Villas-Boas.
The return of David Luiz is also expected to provide a further threat to Alex, and Arsenal are now reportedly ready to take advantage of his possible availability.
The acquisition of added defensive steel has taken on an even greater importance for Arsene Wenger since he saw his Arsenal side demolished 8-2 by Manchester United on Sunday.
Laurent Koscielny partnered Johan Djourou at Old Trafford, but both are likely to lose their places if the Arsenal boss dips into the transfer market.
