Bayern Munich and Liverpool have reportedly joined the race to sign reported Arsenal target Denis Zakaria this month, with Borussia Dortmund also said to be in discussions over a potential deal.
The 25-year-old is set to leave his current club, Borussia Monchengladbach, in the summer, with his contract expiring at the end of the season.
The Swiss international has already refused to sign a new contract, looking to move on to another club with plenty of reported interest in his services.
