John Metgod believes Portsmouth's new Greek signings are key to getting the club back on track.
Midfielder Angelos Basinas - who signed from AEK Athens on the final day of the transfer window - and on-loan Bayer Leverkusen striker Theofanis Gekas have made an instant impact at Fratton Park.
And the Pompey first-team coach has already admitted to being impressed by the Greek duo, saying they could be key to transforming the club's season.
Metgod believes the pair will be a welcome boost for a side whose form and confidence has been lacking in recent weeks.
"The signings we did were good," Metgod told Pompey TV.
"Gekas has got a very good goascoring record, not only in Greece but in Germany, where he played for Bochum first and then Leverkusen.
"And I think Basinas is a very clever, intelligent midfield player. He has a lot of experience and is a good passer of the ball. I think he has good vision."
Pompey have a tough game against Liverpool coming up, with the Reds making the journey to Fratton Park following a superb 2-0 win over title rivals Chelsea last time out.
But Metgod believes the Greek duo can cause problems for Rafa Benitez's side, saying: "They will both be assets to the group and to the squad.
"Hopefully they can produce, starting straight away against Liverpool.
"I think even though it is Liverpool for their first game, they must always play to get three points.
"I am absolutely sure we have got to be motivated - in this situation you must go for the win."
