Bayern Munich have signed the Hoffenheim and Germany striker Sandro Wagner. The 30-year-old will join the Bundesliga champions in the January transfer window after signing a two-and-a-half year contract keeping him at the Allianz Arena until 2020.

Wagner has scored five times for Joachim Löw’s Germany since making his debut earlier this year and a move to Bayern should make him a certainty to play in the World Cup in Russia.

Wagner is delighted to be returning to his home city and said it was an easy decision. He told Bayern’s website. “A long journey is now at an end and I can return to my home, my club. I’m very happy that it’s come off. Bayern are the best club in Germany and one of the best in the world. When I got the offer, I didn’t have to think about it for long.”Wagner, who came through the youth set-up at Bayern, is joining a side 11 points clear at the top of the Bundesliga.

Meanwhile, Kingsley Coman has signed a new contract with Bayern that commits his future to the club until 2023. The France forward, 21, has scored twice in the Bundesliga this season.
