Arsène Wenger has warned his Arsenal players to beware
Napoli's strength on the counter-attack when the sides meet at Emirates Stadium
on Tuesday.
Both sides began their Champions League campaigns with a
victory in Group F and produced an entertaining 2-2 draw when they met at the
Emirates Cup in August.
Wenger says he learnt lessons from that meeting and is
pinpointing Lorenzo Insigne as a key element of the Italian side's ability to
quickly turn defence into attack.
