Arsenal's pursuit of Juventus defender Martin Caceres is set to intensify.

The Daily Mail says the Gunners are struggling to tie up a new contract for William Gallas, while there are doubts about the ageing Sol Campbell and Mikael Silvestre.

Arsene Wenger is also braced for a raid by Inter Milan for his right-back Bacary Sagna, who is seen as a potential replacement for San Siro star Maicon.

Barcelona defender Caceres impressed at the start of his year-long loan at Juventus this season, but the Turin side are reluctant to pay the £10million asking price as they concentrate funds on ambitious bids for Liverpool duo Fernando Torres and Javier Mascherano.

Caceres fits the bill of being a defender who is good on the ball, impressing at centre half or at full back for club and country.
