Reports in Spain yesterday claimed that Alaves could sign Roberto on a permanent deal from West Ham this summer.
Spanish website GasteizHoy claims that the La Liga side has been very happy with the 33-year-old goalkeeper since he joined the club on loan last month despite he has yet to make a first-team appearance for them.
The report says Alaves will only sign Roberto on a permanent deal at the end of the season if they are offered to chance to do as a free transfer.
Since Roberto signed for free and the Hammers continue to pay 75% of his £30,000 per week wages this does not appear to a massive obstacle with the keeper having another year on his contract. The snag could be personal terms with the Spanish club unable to match Premier League wages and they could leave West Ham agreeing to a compensation package as they did with Reece Oxford to reduce the wage bill.
The Spaniard played 10 games for West Ham letting in 21 goals, keeping only one clean sheet, earlier this Manuel Pellegrini named Roberto as the primary reason he failed at West Ham.
