"Yossi is a good footballer, a top-class player," he told the club's website.
"He's got great ability and is someone I have always liked. I actually tried to take him to Tottenham at one time.
"I think he will be a fantastic addition to the squad.
"We have got a lot of fixtures coming up over the Christmas period and in the New Year, so we are going to need a good squad of quality players for that."
