The French champions want Reus, leaving the Gunners free to sign Cavani.
Paris Saint-Germain striker Edinson Cavani could be on his way to Arsenal as the Ligue 1 champions line up Borussia Dortmund star Marco Reus as his replacement, reports CaughtOffside.
The Uruguay international has long been linked with a move away from the Parc des Princes after being asked to play out of position to accommodate Zlatan Ibrahimovic.
Although Cavani has shown good form from his new role on the right flank the 27-year-old is sure to welcome the opportunity to resume his favoured No.9 position at the Emirates Stadium.
The Gunners are long-term admirers of the South American and would look to bring the forward to North London to act as competition for Olivier Giroud and Danny Welbeck.
As for PSG, they have their eye on Dortmund attacker Reus as a direct replacement for Cavani, with the Germany international much better suited to a role out wide.
The future of the 25-year-old remains in doubt as he has a release clause of just €25m that becomes active at the end of this season and many top clubs around Europe have their eye on the German.
Coupled with this is the fact that Dortmund are struggling in the Bundesliga and are joint bottom currently, meaning their best players like Reus may be considering moves away from the Signal Iduna Park.
