Arsenal captain Cesc Fabregas did not train with the rest of the first team on Monday after picking up a hamstring injury in the Gunners' 3-1 win over Burnley at the weekend. The Spaniard found the back of the net before being forced off the pitch with a recurrence of the same problem which kept him out for three weeks earlier in the season. Veteran defender Sol Campbell did, however, join in training and he looks set to recover from a groin problem in time to face the Portuguese side, who will take a 2-1 lead to the Emirates Stadium. Cameroon international Alex Song is available as his two-match suspension does not apply in Europe. Andrey Arshavin and Abou Diaby could both feature after coming off the bench against Burnley, while Mexican Carlos Vela could return to the squad after international duty. William Gallas (calf) is still sidelined, while Aaron Ramsey (broken leg), Robin van Persie (ankle) and Johan Djourou (knee) are long-term absentees.

Porto will be without Brazilian midfielder Fernando, who misses out with a thigh injury. The only other absentee for manager Jesualdo Ferreira is Ernesto Farias with a knee injury. The striker also missed the first leg at the Estadio do Dragao. Porto have lost on all six of their previous trips to London in European competition.
