All or nothing at Donbass Arena

FC Shakhtar Donetsk and FC Porto will both be fighting to stay alive in this season's UEFA Champions League when they face off at the Donbass Arena.

• This season's campaign has not gone to plan for either club who find themselves in the bottom two of Group G, Porto with four points and Shakhtar with two.

• Winless Shakhtar need a victory to revive their fading hopes – and even that will be insufficient if the group's other teams, FC Zenit St Petersburg and APOEL FC, draw in Russia. Porto, whose only win so far came against Shakhtar on matchday one, will be equally desperate for the three points as a draw would eliminate them if APOEL were to lose to Zenit.

Previous meetings
• The clubs' only past encounters came in the 1983/84 UEFA Cup Winners' Cup quarter-finals, António Morais's Porto battling back from 2-0 down to win their home leg 3-2 before drawing 1-1 with Viktor Nosov's Shakhtar in the return.

• The teams for the second leg in Donetsk on 21 March 1984 were:
Shakhtar: Elinskas, Varnavskiy, Goschkoderya, Radenko, Parkhomenko, Rudakov (Petrov 58), Yaschenko, Sokolovskiy, Kravchenko, Yurchenko (Pokidin 81), Grachyov.
Porto: Zé Beto, João Pinto, Eduardo Luís, Lima Pereira, Eurico, Rodolfo (Walsh 66), Jaime Magalhães, Sousa, Fernando Gomes (Barradas 89), Jaime Pacheco, Vermelhinho.

• Porto went all the way to the final, losing 2-1 to Juventus in Basle. It was the first time Shakhtar had reached a major European quarter-final – an achievement they did not match until their triumphant 2008/09 UEFA Cup run.

Match background
• Shakhtar stand on the brink of another early exit from the UEFA Champions League, just 12 months after finally breaking their duck in the competition. Their 2010/11 run to the quarter-finals was their first participation in the knockout phase after six previous campaigns ended in December.

• To give themselves a chance, Shakhtar – held at home by APOEL and Zenit – must recover their once dominant form at the Donbass Arena. They posted four straight home wins in last season's UEFA Champions League before their quarter-final loss to FC Barcelona, a result that ended a 15-match unbeaten European sequence in Donetsk.

• The same could be said of Porto's away form. They managed a seven-match winning streak on the road during their triumphant 2010/11 UEFA Europa League campaign but have lost both away games in Group G.

• Porto have not failed to qualify from the group stage of a UEFA club competition since finishing bottom of their UEFA Champions League section in 2005/06. They have a record of two wins and a draw on past visits to Ukraine, most recently a 2-1 success at FC Dynamo Kyiv in the 2008/09 group stage, in which Rolando equalised and Lucho González hit an added-time winner.

• Shakhtar beat SC Braga 2-0 at home in last term's UEFA Champions League group stage yet that was their first victory against Portuguese visitors. Their record reads: W1 D2 L2.

Team ties
• Shakhtar coach Mircea Lucescu led Romania as they lost 1-0 to Portugal at the 1984 UEFA European Championship, and then won 3-2 against same opponents in a Lisbon friendly the following year. Including the matchday one meeting with Porto, his record in seven games against Portuguese opponents with Shakhtar now reads W3 D0 L4 (W1 D0 L2 at home).

• Souza and Alex Teixeira played together at CR Vasco da Gama in 2008 and 2009, winning the Brazilian second division title in the latter campaign.

• Jadson scored Shakhtar's winner against SL Benfica 1-0 in a 2007/08 UEFA Champions League group match. Cristian Rodríguez featured for Benfica before joining Porto the following season.

• Porto's Cristian Săpunaru and Shakhtar's Răzvan Raţ are international team-mates with Romania.

• Steven Defour featured as Belgium lost 2-1 away to Henrik Mkhitaryan's Armenia in 2010 FIFA World Cup qualifying.

• Porto's Fredy Guarín and Shakhtar's Marcelo Moreno were on opposite sides in Colombia's 2-0 2011 Copa América win against Bolivia.

• Marcelo Moreno got both Bolivia goals in a 2-2 home draw against Rodríguez's Uruguay in a World Cup qualifier in October 2008.
