When the boss signed Christian from Liverpool in July 2001 it appeared that the team would have a perfect balance and a considerable attacking threat down both flanks. Both wing-backs of the highest quality, the pair would offer Glenn the perfect tools to play the 3-5-2 system to great effect.
Or so it seemed...
The staggering fact is that Carr and Ziege have yet to play a competitive first team fixture together. Carr missed the whole of last season with a knee injury and, since he has been back patrolling the right flank, Christian has missed out with a calf problem.
Even though they were both there or thereabouts at the beginning of the season, they have yet to swap crosses in anger on real first team duty.
It is something that Christian wishes to put right very soon.
"Just one game we have played together recently and that was against Feyenoord in pre-season," he recalled. "Even then we didn't play in the shape that the gaffer wanted us to originally.
"So I hope it comes soon!"
Meanwhile, Christian feels that he is unlikely to figure against Arsenal on Saturday despite making an impressive 45 minute return for the reserves on Monday. 'Wait and see' appears to be the message.
"Obviously we'll have to see. It's a big game against Arsenal and not one of those where you could play at, say, 80 per cent. It is a game where you need to be 100 per cent there.
"We will see what the gaffer says."
With any luck in the coming weeks, Glenn Hoddle might, at last, be able to field Stephen Carr and Christian Ziege in the same team.
