Wojciech Szczesny believes that Arsenal were worthy winners in their Champions League Group F encounter with Olympiakos last night.
Alex Oxlade-Chamberlain and Andre Santos were on target in the 2-1 victory, a result which leaves the Gunners second in Group F.
"It was a very tough game. We knew before the game that it was going to be a very tough game,” he told Sky Sports News.
"I think you have to give credit to our defence for keeping the result at 2-1 because they did put pressure on us.
"It was a great defensive performance in the second half. We did very well.”
Arsenal return to league action this weekend when they face North London rivals Tottenham.
