City have been decimated by injuries and setbacks so far this campaign, which has contributed to a dip in form and just one win in nine matches in all competitions.
But the inspirational Portuguese believes as players come back, the team can rekindle their best form - and says when City are at our best, we are unstoppable.
“Our way has always been the same.,” Dias says.
“When we are on a good level, no one can stop us.
“We have injuries, but when we have everyone available, if we find our rhythm we can be dangerous.
“With the team we have, I believe it - believe in ourselves - keep strong, focus and we will find it.”
