Arsenal goalkeeper Manuel Almunia says new teammate Andrey Arshavin is sure to make a huge impact in the Premiership.
"He is clever and looks for that quick, early shot to surprise teams," Almunia told the club's official website.
"I think he will create a mess in the defence of many teams because he is so tricky.
"I am sure he will be a big player for us and help us for the rest of the games in which he plays this season."
