Serge Gnabry has hinted he would be open to a return to Arsenal or even a move to Chelsea after an impressive six months at Werder Bremen.

The German international forced his way out of the Emirates, against the wishes of Arsene Wenger, in the final days of the summer transfer window to return to the Bundesliga and the prospect of regular first team football.

Gnabry has made the most of the more regular opportunities afforded to him at Werder Bremen, scoring seven goals for his club side and earning a call-up to the full German squad. The 20-year-old made the most of his opportunity with Die Mannschaft, becoming the first debutant to score a hat-trick in 40 years in an 8-0 win over San Marino.

Rumours of a clause allowing him to move to Bayern Munich persist in the German media but when asked about a possible move away from Bremen Gnabry hinted he may be just as open to a return to England.

He told Bild: “For my future, I've decided to focus on how I play now and today. That's why I'm trying to concentrate on the now.

“As of today, I do not intend to change in the summer. But what happens in the future depends on my performance.

“What if Chelsea or Arsenal come knocking? Well, at the moment I'm trying to give everything to Werder.”

Bremen have been battling to remain in the Bundesliga all season long, their cause hardly aided by a porous defence that has conceded an average of over two goals in their 16 games this season.

Gnabry’s former Arsenal team-mate Per Mertesacker has been linked with a move back to the side he played for between 2006 and 2011, either as a loan signing in January or on a free at the end of the season.

Arsene Wenger’s plans to hand the Arsenal club captain make either possibility remote but Gnabry would be keen for a reunion.

“Per has had a career unlike many footballers,” Gnabry added. “He has enough experience to decide his future.

“Because he’s a good buddy of mine, I'd be happy to play with him, of course.”
