Everton's manager, Roberto Martínez, is making swift progress in the transfer market after the club added the signing of the Atlético Madrid goalkeeper Joel Robles to that of the defender Antolín Alcaraz a couple of hours earlier.

The pair worked with Martínez at Wigan Athletic and have joined the striker Arouna Koné, who signed a three-year deal with the club on Monday after leaving the DW Stadium.

Martínez brought the 23-year-old Robles in on loan at Wigan and he soon displaced Ali al-Habsi as first choice and featured in the FA Cup final win over Manchester City.

Robles has signed a five-year contract for an undisclosed fee.

Alcaraz, a 30-year-old Paraguay international, has agreed a two-year deal after being released by Wigan.

Last season was a difficult one for the defender as a groin injury sustained on international duty ruled him out for six months from late August.

Martínez has said previously if Alcaraz had been fit for the majority of the season Wigan would not have been relegated.
