Arsenal take on Greek champions Olympiacos in match day two of their Champions League Group B campaign at Emirates Stadium tomorrow night.
Here we look at who could influence the match in north London.
VITO MANNONE v ROY CARROLL
Olympiacos' hopes of taking anything from north London are likely to rest on whether their former Manchester United goalkeeper Roy Carroll can keep the Gunners strikers at bay. Carroll, recently recalled by Northern Ireland, has started all five of Olympiacos' domestic wins but was left out as they lost their Champions League opener 2-1 to Schalke. At the other end Mannone has ably deputised in goal for the injured Wojciech Szczesny.
SANTI CAZORLA v DJAMEL ABDOUN
Cazorla has taken no time to establish himself as the creative force of Arsenal's midfield following his summer move from Malaga. The 27-year-old's intelligent movement and passing is likely to be a handful for the Olympiacos' engine room with Algeria international Abdoun, who scored the Greek side's only goal in the defeat to Schalke, their main threat.
GERVINHO v JOSE HOLEBAS
Gervinho has frustrated and delighted Arsenal fans in equal measure already this season but a return of four goals in his past four starts means the Ivorian is in goalscoring form. Greece left-back Holebas, who was born in Germany to Greek and Uruguayan parents, will look to quell his influence from the wide positions.
