Eduardo is fit to face Portsmouth this weekend despite an 11th-hour withdrawal from Arsenal's Champions League win at Celtic.

The Croatian striker was named among the substitutes at Parkhead but was replaced on the bench by Jack Wilshere just before kick-off. Arsène Wenger explained why when he spoke to Arsenal TV Online at the training ground on Thursday.

"Eduardo had a tight groin in the warm-up and he felt he could not play," said the Frenchman. "He had no power and we had to change [the teamsheet] quickly.

Wenger reported no new injuries from that bruising encounter in Glasgow but, on the flip side, none of Arsenal's injured quintet are fit to return. The manager was hoping to call on Theo Walcott for the first home game of the season but his back problem has still not healed.

"I don't believe we have anyone injured from Tuesday night's game at Celtic," said Wenger. "Eduardo I believe will be back in contention but Theo Walcott will not be back at all. Rosicky, Djourou, Nasri, Fabianski - they will all be out.

"There is a slight concern [over Walcott's back injury] but we believe it is a question of days and not of weeks.

"We will see [if he is fit to face Manchester United next Saturday]. It is always difficult to set a date. I thought he would be available for Celtic, I thought he would be available for Everton, but he wasn't. That's why we will be cautious."
