Summer break: Mertesacker enters the final year of his contract in July

Serge Gnabry is set to join Werder Bremen after advice from his Arsenal colleague Per Mertesacker.

The Bundesliga club have revealed on their official Twitter account they have reached an agreement with the London giants over the signing of winger Gnabry.

Bremen director Frank Baumann said documents have not yet been signed but the club are confident they will land the Arsenal 21-year-old before the transfer cut-off on Wednesday night.

Bremen also revealed that their former player and Arsenal captain Per Mertesacker has been key in convincing Gnabry to join them and  former club and snub interest from Bayern Munich.

Reports from Germany on Tuesday said the Arsenal wide player was to join Bayern in a £6.8million deal before being loaned out to Bremen.

However, it now seems that the Bundesliga champions are out of the picture and that the Gunners are dealing directly with Bremen.

Bremen released a series of tweets to underline that they are confident of securing the services of the German winger.

Baumann said: “We have reached an agreement in principle with Arsenal, but it is not signed yet.”

Arsenal club captain Mertesacker was also said to be instrumental in the deal, offering advice to Gnabry  about his former club.

Baumann said: “Gnabry has told us that Mertesacker was ‘full of praise’ (for the club).”

Wenger still has faith in Gnabry even though he hasn’t appeared for the north London club since March 2014.

“I want to keep Serge Gnabry and extend his contract. I think we stood by him,” said Wenger 10 days ago, as quoted by the Sky Sports on their transfer centre blog (9.23am). “He went to West Brom, didn’t play, we had to rebuild his confidence.

“I allowed him to go to the Olympics to help Germany. I think he’s here now for a long time.”

The youngster had a disappointing loan at Premier League rivals West Bromwich Albion last season, where he was recalled after making just three appearances for Tony Pulis’ side in all competitions.

However, Gnabry had something of a rejuvenation over the summer, as he helped Germany to a siver medal in the Rio Olympics, scoring six goals in the process, putting in some outstanding performances.

The seven-time capped Germany Under-21 international was highly rated when he broke into the Gunners first-team after he made his professional debut in the 2012-13 season against Coventry in the League Cup.
