Baston wants to stay at Malaga beyond his season-long deal after revealing his Liberty Stadium woes.
"It wasn't the experience that I thought, but everything is experience and I draw good conclusions," he told AS, summing up his frustrating time with the Swans.
"To make a good year, everything matters.
"It was not like I expected. I arrived with a wrist injury that I suffered in pre-season with Atletico and I didn't play until week seven or eight. I was not happy, but I learned from it.
"I would like the purchase option exercised (at Malaga)."
