However, it seems Valencia are on the cusp of signing Bustos, who has become a prolific goalscorer.
Details of the transfer have not been finalised, but Bustos would be part of an overhaul at Valencia.
The La Liga club want to improve their attack with only Maxi Gómez safe from the axe this summer.
In the 2019-20 season, Bustos scored nine goals in 20 matches for Talleres, while contributing four assists.
Bustos is also an Argentina under-23 international and spent some time on loan at Pachuca in Liga MX.
