Borussia Dortmund's German international midfielder Ilkay Gundogan, who underwent a back operation that saw him miss the FIFA World Cup™, should make his return in three months, the Bundesliga club announced on Thursday.

Gundogan "was successfully operated on at the start of the week in Munich to ease a pain in the spine", Dortmund said in a statement, adding that doctors envisaged a three-month rehabilitation schedule. That means the 23-year-old will likely miss the start of the Bundesliga on 22 August and also the 16 September kick-off of the UEFA Champions League, for which Dortmund qualified as runners-up of the German league.

Gundogan has not played for Germany since his injury, sustained in the national team's 3-3 draw with Paraguay in August 2013. In that time he has played just three games for Dortmund: the German Supercup, a first round match of the German Cup and the first Bundesliga match of last season.
