London  - Eduardo marked his return to first-team action with two goals on Monday as Arsenal beat Cardiff City 4-0 in the fourth round of the FA Cup.

The Croatia forward hadn't played since breaking his leg against Birmingham City last February.

But he started well, and after 20 minutes headed the opener from Carlos Vela's dinked cross.

Nicklas Bendtner made it 2-0 14 minutes later, heading in from a corner.

Only a handful of fine saves from Cardiff keeper Tom Heaton kept the score down.
