Following an unhappy spell being unable to break into the Liverpool side, Ziege decided that his future lay away from Anfield. In July 2001, Tottenham signed the German international for around £4 million.
Starting his career in lower league clubs in Germany, he soon attracted the attention of Bayern Munich, only leaving there to go to AC Milan. Found pushed into the shadows in Italy, Middlesbrough took him on and he did well there for a season until Liverpool made great efforts to prise him away from the Riverside. It is surprising then, that having paid £5.5 million for the player, that they then proceeded to play him only sporadically and he eventually did not fit into the pattern that they were to play. Some controversy surrounded his move to Anfield and later, a claim that the Merseyside club had been tipped off about a clause in his contract allowed them to sign him for less than his true vale, thus incurring a fine from the FA.
With the World Cup 2002 in Japan and Korea, Ziege needed to be playing first team football to ensure he was included in the German squad and thus he went up for transfer. A proposed move back to Germany with FC Schalke 04 fell through, allegedly because they could not meet his wage demands, although the official excuse was he was not the type of player they were looking for. Tottenham then was his only outlet and he showed in the friendlies in pre-season for 2001-02 that he could add an attacking dimension on the left wing to match that of Carr on the right. His addition to the squad also strengthened the weakness that had been evident on the flank for a number of years.
Won his 60th cap in August 2001 as a sub in a friendly against Hungary and went on to start in all the German World Cup 2002 games apart from the Final, in which he made an appearance from the subs bench.
Started the 2002-03 season injured from a pre-season match, but returned quickly to add his crossing skills to the side. He also scored some cracking goals (free-kick against Arsenal and a scorcher against WBA), before suffering a seemingly innocuous knock against Charlton Athletic at Christmas, which saw him rushed into hospital after the game. One emergency operation later and he had been saved from losing his leg and maybe his life after the muscle had gone into a case of compartmentalisation syndrome. This ruled him out for the rest of the season, but his good progress, considering the doctors thought he might not play again, saw him feature in the last game of the season at home to Blackburn Rovers.
Just when he had been training throughout the summer to build up his leg, he took a knock against Wycombe Wanderers and the muscle had produced some pain, which kept him out for almost another three months. Spurs missed his supply line from the left in his absence, but returned to the side late in the season which coincided with a poor run at the end of the 2003-04 season.
Christian was allowed to leave the club in the summer of 2004 to join German side Borussia Moenchengladbach on a free transfer.
Ziege was a true professional and brought his experience and quality to the Tottenham side, when it would have been easy for him to go through the motions and pick up his wage packet. His crossing and free-kicks were the most stand-out contributions, but his general help to other players and the level of performance make him one of the better imports Spurs have signed through the years.
