Mikel Arteta has said Arsenal's summer signings are enabling his team to "become more unpredictable" after new-boys Martín Zubimendi and Noni Madueke starred in Saturday's 3-0 win over Nottingham Forest .

Arsenal spent more than £260 million ($352m) on eight summer signings, five of whom started at Emirates Stadium on Saturday.

Arsenal lost captain Martin Odegaard to a shoulder injury after just 18 minutes but dominated Forest regardless with Zubimendi opening the scoring just after the half-hour mark through a sumptuous volley from the edge of the box.

Viktor Gyökeres , a £63m ($85m) summer acquisition from Sporting CP , netted his third goal in four games as Eberechi Eze marked his full debut with an assist.
