Now becoming their worst start since 1994/95, Suarez could not hide his disappointment at the result.
"It's a defeat which is concerning and hurts, we have to look very closely at many things," Suarez said.
"We need to take a look at ourselves to be able to improve.
"After starting by going behind in the first few minutes, it made things difficult, we weren't decisive."
"You can't mix this with last year, we have to analyse the first games we've played away," he explained.
"Obviously it's worrying, alongside the lack of efficiency and chances."
