Has Gallas played his last game for Arsenal?

One of the first things I would do, if I could be in Arsène Wenger’s shoes this month, is sell William Gallas.

Talking with fellow Addicts after last Saturday’s win over Plymouth, I agreed that he has come up with some vital goals this season and that when he is on form, he is probably our best defender.

But he fact is, Gallas is hot and cold. Sometimes he plays like a real warrior, other times (Birmgham away for instance), he sulks and shows none of the authority a player in his position should exhibit - regardless of whether he is captain or not.

Just look at the tackle he made in the second half against Aston Villa which let the home team back into the game.

It was the tackle of an infant and left us scrambling for our lives and then lamenting a missed opportunity when simply shepherding his opponent out would have probably killed the game.

While Kolo Toure has been a shadow of his former self ever since the African Nations’ Cup, he is much younger than Gallas, plays in a similar manner and has the heart of the club deeply engrained in him.

There has been much speculation that the Ivorian doesn’t get on with Gallas and will be on his way, but I know who I’d rather keep and it’s not Gallas.

Rows go on at all clubs – but the fact is that you don’t hear about them.

The fact that Gallas went public and criticised his team-mates will also have left a scar and too many of them are too young to be able to move on from it.

Remember, it’s clear to see that Arsène Wenger doesn’t have a lot of money at the moment – and getting rid of a player who is one of the club’s top earners must make economic as well as tactical sense.

Sadly, the injury that will rule Gallas out for much of the rest of January could hamper any possible move away from the club – which must have been considered even if Wenger has denied it.

Some have suggested that we should bring Big Phil Senderos back from his loan at AC Milan, but I have it on good authority that he has not been a success in Italy.

When he played the second half against Hamburg this week during a friendly in Dubai, he was booed amid chants of “Go back to Arsenal”. It can’t help that he replaced Paolo Maldini. Even at 103, the Italian legend is a better player than Senderos.

I still hold out hope that Wenger realises he needs a new defender and for all the reasons I’ve given, selling Gallas makes the most sense.

Who to replace him? If not Fulham's Brede Hageland, how about Real Madrid outcast and Germany international Christoph Metzelder, or Dorin Goain from Steau Bucharest who has all the tackling, heading and passing ability we need...

What do you think? Should we cash in on Gallas or keep him until the end of the season?
