Arsenal could make a renewed bid to sign long-standing target Mario Gotze after reports in Germany revealed that the Borussia Dortmund playmaker has a £30m release fee clause in his contract.
Gotze, 20, is regarded as the brightest young player in German football after helping Dortmund to back-to-back Bundesliga titles.
Arsenal offered the German champions £32m for the midfielder in the summer of 2011 but the bid was rejected.
Gotze signed an improved deal with Dortmund in March, tying him to the club until 2016.
And according to BILD, the new contract includes a buyout clause of £30m - £2m less than the figure Arsenal offered last year.
But the clause expires next July and interested clubs are required to submit a written offer by the end of April 2013.
Bundesliga heavyweights Bayern Munich are also long-term fans of the 20-year-old and could rival Arsenal for his signature.
