Glenn Murray's penalty and Shane Duffy's bullet header cancelled out Rodrigo's opener, and Potter reflected on a promising evening at the Amex.
He said, “I thought we grew into the game, didn't let the disappointment of going a goal down affect us, and kept trying to do what we wanted to do — there were some really good performances out there.
“While the result doesn't necessarily matter, it's nice to win as well. The second half was full of good play and positives to carry forward.
“The players were still going towards the end and looking to press. Valencia changed a lot of players, so we were playing against a fresh team in the second half.
“We'll use every minute that we can to carry on improving, as we prepare for Watford."
