Hertha Berlin have said they do not believe Liverpool will get a work permit for Brazil under-20 international Allan as they prepare to open talks to extend his loan into next season.
Allan, 20, joined Liverpool from Porto Alegre in 2015 but the midfielder has yet to appear for the Premier League club, having spent time with SJK in Finland and Sint-Truiden in Belgium before spending the current campaign with Bundesliga club Hertha.
However, Hertha's failure to qualify for Europa League, and Allan's participation in the South American Under-20 Championship at the beginning of the year, has limited his opportunities, with the Brazilian appearing just 12 times in all competitions.
