Tests conducted on Norway and Arsenal midfielder Frida Maanum showed "no obvious cardiac causes" following her collapse during the Women's League Cup final but she will have a device fitted to monitor her heart function, the club said on Thursday.

The 24-year-old slumped to the turf during second-half stoppage time of the final against Chelsea, receiving treatment on the pitch for almost 10 minutes before being replaced, with Arsenal going on to win 1-0 after extra time.
