Sept 6 (Reuters) - Liverpool are in touch with authorities to safely bring back midfielder Naby Keita following a military coup in his homeland of Guinea, the club said on Monday. "We are in constant contact with Naby and have had regular communication via his national team management," Liverpool said in a statement. While the country's borders have reportedly been closed, the Moroccan team were allowed safe passage home later on Sunday. Keita started Liverpool's opening two league games and was an unused substitute in the 1-1 draw against Chelsea. Liverpool next face Leeds United on Sept. 12 after the international break.
