Real Betis are reported to have stepped up their efforts to sign Valencia winger Mario Regueiro.
Los Verdiblancos are in the market for a left-sided midfielder and have been weighing up several options this summer.
Ze Roberto, Ludovic Delporte and Jonathan Sesma have all been considered, but Regueiro is thought to be coach Javier Irureta's preferred option.
Reports claim that Betis, who attempted to sign Regueiro last summer, have tested Valencia's resolve with a bid of é¼5 million (£3 million).
Valencia have thus far refused to play ball and are looking to keep Regueiro as cover for injury-prone winger Vicente.
However, Betis look unlikely to give up their pursuit, especially as they loaned left winger Juanlu to Osasuna earlier in the week.
