Arsenal boss Arsene Wenger will face a selection dilemma in the Champions League tie at Porto next week as Andrei Arshavin will miss out. The Russian forward sustained a hamstring injury in the 1-0 Premier League win over Liverpool and confirmed his absence. "If all goes well, I get back on the pitch as early as the next Premier League match against Sunderland," Arshavin told Sport Express. "However, the next game against Porto in the Champions League I will miss." Arshavin, a natural playmaker, has been deployed as the Gunners' main striker in recent weeks, amid the long-term injury of Robin van Persie.
