Arjen Robben believes Chelsea have the mental strength to recover from their recent problems.
The Blues' grip on top spot in the Premier League was loosened following a dramatic 4-2 defeat at home to Manchester City on Saturday.
But it is events off the pitch that have made unwanted headlines in recent weeks, following allegations of infidelity involving John Terry and Ashley Cole.
Bayern Munich winger Robben admits it has been a tricky period for Chelsea, where he spent three years from 2004 to 2007.
Robben, currently preparing for Holland's friendly against USA on Wednesday night, hopes his former club can bounce back and enjoy success on the field.
"It is a difficult time," he told Sky Sports News. "It is not good for the club or football in general but these things happen.
"I think it is going to take a long time for people to forget about it but they have to handle it.
"I think they are strong enough and they have so much quality. Also mentally they are up for it I think."
