The Algerian international has joined the Hammers on a three-year deal.
The Hammers announced the free transfer of the Algerian yesterday and he spoke of his desire to get his Premier League career under way in his first interview with the club.
“What he achieved last year was incredible and fully deserved as he worked hard to get to there,” said Feghouli when asked if he could have a similar impact to Mahrez.
“I have my own objectives, I am ambitious and want to achieve great things in Europe with the Hammers and to leave my mark.”
Feghouli’s capture is a coup for West Ham after the likes of Tottenham and Manchester United were also linked with the pacey winger, as reported by talkSPORT.
Signings of this calibre are necessary if the Hammers are to build on a great campaign last year and establish themselves among the top clubs in the Premier League.
Further signings are likely to arrive as manager Slaven Bilic looks to add strength in depth to his already talented squad and one possibility is French sensation Alexandre Lacazette.
Recent reports by the likes of The Sun claim West Ham have seen a £32 million offer knocked back for the 25-year old and will need to get closer to £40 million if they are to land their man.
The calibre of player currently being linked with the Hammers is a clear indication of the progress enjoyed at the club in recent years and with substantial investment now being pledged into the squad, that progress looks set to continue.
