The Welsh region have now lost back to back pre-season clashes, first against Leicester Tigers and then against Bath Rugby this weekend.
The latter defeat came with Tandy forced to field an inexperienced outfit but the head coach admits his side will need to improve before their season opener against Zebre.
Before that they will head to Welford Road for a re-match with Leicester in pre-season and Tandy is not panicking just yet after late tries from Josh Thomas and Owen Watkins gave them hope in a 28-14 defeat to Bath.
“There is still a hell of a lot of work before Zebre in two weeks time,” he said.
“It is hard to put in inexperienced players, but we have got Leicester on Friday, and we will have some other guys back in the mix.

“It was a tough afternoon, we had a pretty young team going up against an experienced Bath team — we have a fair bit to work on before we go to Leicester next week,” admitted Tandy afterwards.
“We know we have to tidy up on our set-piece, but I thought the boys hung in there, there were some decent performances, I thought Cory Allen played pretty well, Hooky as well and Rob McCusker up front.
“It was a big good experience for the young boys, the harsh reality of top-end sport is that you can get torn up if you don’t do the basics properly.”
Elsewhere Glasgow Warriors had their first game under Dave Rennie and slipped to defeat to Northampton Saints in Stirling for the new Kiwi head coach was feeling positive.
Speaking to glasgowwarriors.org, Rennie said: “I’m really proud of the boys.
“We had a lot of young guys out on the field today, a lot of boys in their first hit out for the Warriors. They stood up really well.”
Dave Rennie was upbeat following the narrow defeat to @SaintsRugby in Stirling yesterday.
