Olivier Giroud is refusing to get excited about Arsenal's Premier League title chances after helping them briefly to the top of the table.
Giroud, 30, struck twice inside five minutes with his first two touches after being introduced as a second-half substitute to contribute to a 4-1 victory at Sunderland on Saturday.
That allowed the Gunners to leapfrog Manchester City into first place, but only for a couple of hours as Pep Guardiola's men moved back above them on goal difference after a 4-0 win at West Bromwich Albion.
"We've only played a quarter of the league," Giroud told Arsenal's official website. "It's still the beginning of the league and I'm not the man who will speak too much because we are first.
"We enjoy this position, obviously we want to finish first and win the league, but we know there is a long time to go. We're in a good moment and we need to keep it up and be consistent.''
Giroud was making his first appearance in the Premier League since September, having struggled with a toe problem, while Aaron Ramsey also made his comeback from a hamstring injury, which had kept him out since the opening day of the season.
Arsenal manager Arsene Wenger was pleased to see them back on the pitch ahead of Tuesday's Champions League clash against Ludogorets Razgrad.
"With Giroud back, Ramsey back, [Granit] Xhaka is not suspended anymore," Wenger said. "So overall, I think we are in a good position.''
