After a miserable time with the Hammers the Brazilian finally saw his loan spell agonies in Portugal come to an end with the Hammers agreeing a £4 million fee with his former club Lazio.
The player had hit a slump from which some wondered whether he would ever re-emerge but the return to Serie A and his familiar surroundings has worked the oracle.
The £35 million Hammers signing is showing himself to be a fine footballer again and on Sunday was the star of the show as he showed against Roma when scoring one and providing a glorious assist.

Anderson set up one goal against Roma, a glorious floated cross powered home by Sergej Milinkovic-Savic, before tapping in himself following fine approach play from Ciro Immobile.
