Wigan Athletic boss Roberto Martinez is being linked with Espanyol.
Local radio Cadena SER says Espanyol management are losing confidence in Mauricio Pochettino as they struggle to move away from the relegation zone.
No immediate decision is expected, but Espanyol directors have drawn up a shortlist of potential replacements - with Martinez high on the agenda.
The Spaniard is in his first season in charge at Wigan after successfully taking Swansea City from League One to the Championship.
