In December 2005, Katan signed a four-year contract with
West Ham United, where he joined up with Israeli international teammate
Yossi Benayoun. The transfer, which was officially completed during the January 2006
transfer window, involved a cut-price fee of £100,000, as Katan had only six months left on his Maccabi contract. He made eight appearances, including six from the bench, for West Ham. At the end of the 2005–06 season, Katan moved back to Maccabi Haifa in a loan deal, with a view to a permanent move, after
Alan Pardew reportedly told him he was no longer in his plans. He returned to Israel and made his loan deal permanent by signing a new four-year deal with Haifa. After 25 years in
Maccabi Haifa, on 19 June 2014, Katan decided to retire from active playing. On 5 April 2015, a farewell ceremony for Katan was held at the
Sammy Ofer Stadium on which both
Maccabi Haifa's chairman
Ya'akov Shahar and Katan led a speech and the fans held a giant flag with Katan's pictures. ==Career statistics==
