Manchester City boss Pep Guardiola has warned his team against Napoli's threat after turning his attention to Europe.
Leroy Sane, Fernandinho and Raheem Sterling scored in a comfortable 3-2 win for the visitors at West Brom on Saturday.
The scoreline flattered Albion who, despite battling, were outclassed by City as Guardiola's men recorded their eighth straight Premier League win.
They are five points clear at the top and have won 13 games in a row in all competitions and are unbeaten in their last 21 outings - two new club records.
