With Jon Flanagan's persistent injury problems and Javier Manquillo's uncertain future, Liverpool are in need of a new fullback this summer. Right back Nathaniel Clyne has been the top target for the club so far, but recent reports indicate that out of favor Alvaro Arbeloa could make a return to Liverpool if deals for other players don't materialize.
Arbeloa, who played two seasons at Anfield before leaving for Real Madrid in 2009, has been a regular in Spain since his arrival, but the emergence of Dani Carvajal and the reported purchase of Danilo has him on the outs at his current club. As a 32-year-old fullback with declining skills, it wouldn't be surprising to see him move elsewhere this summer in an effort to get more consistent playing time before the end of his career.
If Liverpool were to sign him, Arbeloa would add much needed depth to the fullback position while providing fans with a nice reunion story. He also wouldn't cost much. However, Liverpool just bid farewell to a right back on the wrong side of his career arc, and given that Arbeloa would be a stopgap rather than a solution, further funds may need to be invested in an additional fullback if he's purchased.
