The Swiss international has spent the first half of the season with Bundesliga side Greuther Fürth.
Fürth are stranded at the bottom of the table with just one win in 18 games. For Itten, he has made 12 appearances with just five starts, netting two goals, including one in a 3-1 defeat to Bayern Munich.
It is understood Itten doesn’t fit into the way Fürth boss Stefan Leitl wants to play.
The decision suggests he could feature under new manager Giovanni van Bronckhorst.
The 25-year-old has played for two clubs this season already having feature four times under Steven Gerrard before his switch to Germany.
Van Bronckhorst’s forward options include Alfredo Morelos, Fashion Sakala, Kemar Roofe and Jermain Defoe.
Roofe has had a recent injury issue, while Defoe has featured just once under Van Bronckhorst.
