APOEL will be without new striker Mikael Pote for their crucial Champions League second leg qualifier against Viitorul on Wednesday.
The Cypriot champions had sacked coach Mario Been – who had only been in charge for three games – in the wake of the defeat at the hands of the Romanian title holders and swiftly replaced him with former boss Georgios Donis.
Greek coach Donis had led APOEL to a league and Cup double as well as the group stages of the Champions League back in 2014.
But he now faces his biggest challenge yet in Nicosia with his side trailing 1-0 and without Pote available and talented winger George Efrem being rushed back from injury for the third qualifying round, second leg at the GSP Stadium on Wednesday.
APOEL officials expect around 14,000 spectators for the second leg.
Elsewhere, Apollon Limassol will be looking to overturn a 2-1 deficit against Aberdeen in their second leg Europa League qualifier in Larnaca on Thursday.
The Limassol club will be without suspended coach Sofronis Avgoustis.
AEL drew 0-0 in their first leg away to Austria Wien and will be at the Antonis Papadopoulos Stadium in Larnaca for the second leg on Thursday.
AEK Larnaca will be in Moldova defending a 2-0 aggregate lead against Dinamo Minsk.
