RB Leipzig face an anxious wait to find out the extent of a possible injury to star midfielder Naby Keita.

The 22-year-old opened the scoring in the 2-0 win at Hamburg, but left the field of play late on with what the club subsequently confirmed to be a left groin problem.

Any injury would put a real dampener on what was an impressive display on the road from last season's Bundesliga runners-up, who begin their debut UEFA Champions League campaign at home to Ligue 1 champions Monaco on 13 September.

Liverpool-bound Keita registered eight goals and as many assists in 31 Bundesliga appearances in 2016/17, and has started all three of Leipzig's top-flight outings so far this term.
