The former Real Madrid man could impress for Forest in the same way Michel Salgado fared for Blackburn Rovers - brilliantly.

As Nottingham Forest are in need of a right back to provide quality cover and depth, one wonders if Mark Warburton and director of football Frank McParland are keeping an eye on Alvaro Arbeloa's situation following his release from West Ham United.
It may be unlikely that Arbeloa - formerly of Real Madrid and Liverpool - would rejoice at playing in the Championship after a glittering career, but it's a question that Forest should at least consider asking him, as the results could be hugely beneficial to the team and squad.

A man who's won the World Cup, Champions League, La Liga and the European Championships among other things, available on a free, would be a resounding coup for Forest - assuming that they could come to a financial agreement with Arbeloa.
Despite the fact the former Spain international is 34, there's no doubt he could be hugely influential for Forest, as Blackburn Rovers proved when they signed Michel Salgado - also a right back - in his advancing years, to great success.
Real Madrid's Alvaro Arbeloa is thrown into the air by team mates after the match.
Given the player's stature, it's highly likely that interest from the MLS or Asia will beckon - or even retirement given he only made four appearances for West Ham - but it's possible that he could want one last chance in English football before hanging up his boots.
It's perhaps wishful thinking from a Forest perspective, but if they could land Arbeloa, their new owner Evangelos Marinakis would be making a colossal statement about his intentions to take Forest back into the Premier League.
