Croatia boss Slaven Bilic is backing Eduardo Da Silva to be a big hit at Arsenal.
"He will fit in straight away. Like any Brazilian player, he can play football. When I was thinking about which club suits his game - when he asked me a few times - Arsenal were the first choice because they play football more than any team in England. And he can definitely cope with the pressure."
Da Silva had also attracted interest from Arsenal's north London rivals Tottenham, as well as PSV Eindhoven, Sevilla and Shakhtar Donetsk, but his Dinamo Zagreb coach, Branko Ivankovic, explained Arsenal's bid was "impossible to refuse".
He said: "A transfer was inevitable. We could not stop Dudu from achieving his sporting goals."
