The Swiss midfielder has promised that the Partenopei will bounce back at Signal Iduna Park, after slipping to a surprise domestic defeat to ParmaGokhan Inler has vowed that Napoli fans will see a vast improvement in their side in Tuesday's crucial Champions League clash with Borussia Dortmund.
The midfielder was speaking after Saturday's shock 1-0 defeat to Parma at the San Paolo, a result that condemned the Partenopei to back-to-back Serie A defeats for the first time in almost a year.
The Swiss international acknowledged that changes do need to be made, but he is still confident that they can stop the rot when they visit Signal Iduna Park.
“After the defeat against Juventus we were hoping to redeem ourselves but instead we’ve suffered an unexpected defeat,” Inler told reporters.
“Parma have closed down well in all areas but we have to be more ruthless. We weren’t able to open the game up and so Parma has had an easy time of it.
“It will be a completely different game and a whole other Napoli [in Dortmund]. We have to make sure we get back to our best.”
Dortmund's preparation for the crunch European fixture haven’t gone to plan either, with last year’s beaten finalists routed 3-0 by rivals Bayern Munich on Saturday.
