British newspaper The Sun suggest that the Bundesliga forward is keen to leave the German club and has been made available for a cut-price £15m.
Palace have designs on strengthening their attack after a disappointing season in front of goal, with only relegated Norwich City scoring fewer times in the Premier League than the Eagles last campaign.
Chairman Steve Parish has faced criticism in recent transfer windows for a reluctance to invest in the playing squad, with manager Roy Hodgson repeatedly hinting in press conferences that Palace need to add to their ageing squad.
Following 7 straight losses at the end of last season, many Eagles fans will hope that wretched run of results will encourage the chairman to put his hand in his pocket.
Mainz striker Mateta barely featured in the Bundesliga this season due to a series of frustrating injuries, but 14 goals in 2018/19 for the 23-year-old and 20 strikes the season before for Le Havre show that the 6’3” frontman has potential.
Whether £15m is a gamble worth taking on the Frenchman remains to be seen, but it is of paramount importance that the conundrum up front is solved at Selhurst Park.
