Chelsea face an uphill battle to sign Real Betis midfielder Benat.
Chelsea have Benat under consideration as a replacement for the departing Frank Lampard.
However, the stumbling block is Blues boss Rafa Benitez, who doesn't get along with Benat's agent Inaki Ibanez, says Estadio Deportivo.
Benitez first fell out with Ibanez after clashing over Xabi Alonso's move from Liverpool to Real Madrid.
