In a club release, Bayern sporting director Hasan Salihamidzic said: “We’re very pleased with how Chris Richards has developed with us, which is why we’ve extended his contract.
“Chris is a young player who will now gain further Bundesliga experience at Hoffenheim, which is exactly what he needs.”
Hoppe on the move
Richards wasn’t the only USMNT player to move on deadline day, as Matthew Hoppe joined La Liga side Mallorca from Schalke.
Schalke have been looking to offload Hoppe as they raise funds following their relegation from the Bundesliga last season.
“The financial aspect of this offer meant that in our current situation, we had to accept,” Schalke sporting director Rouven Schreder said in a club release.
“Matthew is a brilliant young player, but he would have found it tough to obtain the regular starting place in this team in the next few weeks that he wants. We wish him all the best for his personal and sporting future.”
Hoppe, 20, scored six times in the Bundesliga for Schalke in a breakout campaign last term.
Neither Richards nor Hoppe was named to the most recent USMNT roster, as Gregg Berhalter’s side gets set to open World Cup qualifying at El Salvador on Thursday.
