Manuel Pellegrini believes West Ham's record signing Felipe Anderson has added quality to his team.
The 25 year old Brazil midfielder signed for a reported £33.5million, potentially rising to £42million, from Lazio on Sunday.
"We feel he will bring a new dimension to the squad but also complement the attacking players we already have," manager Pellegrini said.
"Felipe has a very natural and skilful ability, in the traditional style of Brazilian football, but has proven at Lazio that he also has the strength and mentality to play at the top level in European football," the Chilean added.
