Arsenal may just have been handed a rather timely boost in the transfer market, with reports claiming that Luiz Gustavo has a release clause in his Wolfsburg contract.
According to reports cited by German newspaper Bild, Gustavo - who joined Die Wölfe from German treble-winners Bayern Munich this summer - has a clause in his deal at Volkswagen Arena worth a reported €25 million.
Arsene Wenger's side were also frequently linked with a move for Gustavo this summer, but he eventually neglected that interest from the Gunners in order to remain in the Bundesliga.
However, speculation surrounding the Brazil international's future appears to have intensified once again following this news, with rumours suggesting that Arsenal could re-ignite their pursuit of a player also supposedly interesting La Liga giants Barcelona.
Wolfsburg director Klaus Allofs appeared keen to stress that none of the club's players were immune from departure, but also insisted that all deals have to make sound sense for the club.
"Even at VfL [Wolfsburg] nobody is unsellable," he was quoted by the Daily Express.
"For me it is important that we show [players] that we are willing to negotiate if an offer is made that is reasonable in a sporting sense and also makes good business sense for VfL."
Arsenal, who currently sit top of the Premier League table after amassing 28 points from their opening 12 games, will look to extend the lead over their title rivals with a home clash against newly-promoted Cardiff City in the Welsh capital on Sunday.
