Celtic take on Spartak Moscow in match day two of their Champions League Group G campaign at the Luzhniki Stadium tomorrow night.
Here, we look at who could influence the match in Moscow…
JUAN INSAURRALDE v GARY HOOPER
Insaurralde, 27, is new to European football having signed from Boca Juniors for a reported fee of 3.25million euros (£2.6million) in the summer. The Argentina international will face an on-form Hooper who has scored six goals in his last three matches. The former Scunthorpe striker, 24, comes alive in the box and if the likes of Kris Commons or James Forrest can provide the service then Celtic have a chance.
AIDEN McGEADY v MIKAEL LUSTIG
Much of the attention in this fixture will be on Scots-born Republic of Ireland wide-man McGeady who moved from Celtic to Spartak in 2010. McGeady has more than a few tricks in his repertoire and can play on either wing. However, he may fancy taking on Lustig, set to play at right-back if Adam Matthews fails a fitness test, rather than the pacier Emilio Izaguirre. Lustig is tall and decent in the air but it will be his concentration which will be tested against the talented former Celt.
EMMANUEL EMENIKE v KELVIN WILSON
Nigeria international Eminike recently signed a four-year deal with Spartak to remain in Moscow until 2016 which shows how highly the Russian outfit rate the striker who was linked with a move to several English clubs including Liverpool and Chelsea. Wilson will have to be at his best to shackle the powerful and athletic forward who was Spartak's top scorer last season. However, the 27-year-old Englishman, having recovered from an Achilles problem which blighted last season, has started this season in the sort of form which won him a move to Parkhead from Nottingham Forest in 2011.
