West Ham are giving a medical to free agent Alvaro Arbeloa with the view to signing him on a one-year deal, according to Sky Sports.
The 33-year-old left-back left Real Madrid at the end of his contract in June.
It is understood the Hammers see the former Liverpool player as a mentor rather than replacement for right-back Sam Byram.
And they are hoping his addition will also liberate Michail Antonio to play further forward from the start of games.
Arbeloa is a veteran of European football with 53 caps for Spain between 2008 and 2013, and over 50 appearances in the Champions League.
He began his career in the Real Madrid academy but made the grade at Liverpool after a successful season at Deportivo La Coruna.
He signed for Liverpool for £2.6m in 2007 and made 95 appearances for the Reds before a £3.5m move to Real in 2009.
