Arsenal could face a difficult battle to hold on to one of their brightest young talents during the summer.
According to reports from German newspaper Bild cited by the Daily Mirror, Serge Gnabry has emerged as a future transfer target for Bundesliga title hopefuls Borussia Dortmund.
Dortmund, managed by the charismatic figure of Jurgen Klopp, are set to lose star striker Robert Lewandowski at the end of the 2013/13 season, with the Polish talisman having agreed to join domestic rivals Bayern Munich.
Those aforementioned reports suggest that Dortmund have already watched the Arsenal starlet on a number occasions and that he could be one of several different types of players that could be considered by Klopp when Lewandowski does depart Signal Iduna Park.
18-year-old Gnabry, who joined Arsenal from Stuttgart back in 2011, has enjoyed somewhat of a breakout season at the Emirates Stadium.
To date, the German youth international has made eight appearances across all competitions for Arsene Wenger's men, including five in the Premier League.
Given his newfound role in the first-team setup, it seems somewhat unlikely that Arsenal would be willing to part with Gnabry.
However, with Bayern Munich performing tremendously under the tutelage of Pep Guardiola, Dortmund will surely have to do everything they can do ensure that they are able to adequately replace Lewandowski.
