A fourth defeat in a row leaves the defending champions' campaign in trouble, with Fleming concerned about all facets of their game
Head coach Stephen Fleming says Chennai Super Kings' 100 per cent losing start to the new Indian Premier League season is starting to take a toll on the squad's self-belief.
The defending champions were beaten for the fourth game in a row after Sunrisers Hyderabad opened their account with an eight-wicket win in Mumbai.
Sunrisers were set 155 to win, a target they reached with 14 balls remaining.
It follows six-wicket losses to Kolkata Knight Riders and Lucknow Super Giants, and a 54-run reverse against Punjab Kings.
On the eve of the tournament, Ravindra Jadeja replaced MS Dhoni as captain but he is yet to open his account - not helped by losing three out of four tosses.
Fleming says the run of form - CSK's worst since 2010 when they last lost four on the spin - is starting to impact on the mental state of the squad.
"Probably each facet [of the game] is a concern, if not at one stage then all together," said the New Zealander.

"We were well outplayed today. We're sort of learning. We've got some issues around player availability and in some areas a little bit underpowered, that we're just looking for players to step up.
"So we've got some learning to do still around our players and our squad.
"And we haven't had any evidence that sort of helps the belief. We are not winning any games. Not being close to winning any games, you get a bit of self-doubt, and the players get a little bit niggly.
"So we just got to work through that pretty quickly and try to find some rhythm and get back in the tournament."
Fleming is currently without Deepak Chahar, the 14 crore (£1.41 million) auction signing who is sidelined with a quad tear, and Adam Milne who picked up an injury in the opening game against KKR.
Their attempts to register their first win of the campaign continue against Royal Challengers Bangalore in Mumbai on April 12.
