Should there be a January transfer window?

Wenger has said that he is against the January transfer window and I saw some posters here agreeing with him. Do you think the January transfer window should be scrapped? What are the reasons for you answer?

Positives:
- one can react to injuries
- one can react to players somehow not fitting in
- one can adjust squads when there is something not working / missing
- the media have a lot of stuff to write about

Negatives:
- the squads get upset by players coming and leaving
- players are possibly cup-tied and can't play in EL/CL

So there are both good and bad things about the Winter Transfer Window. I guess allowing Winter transfers allows for more flexibility, so it is not that bad.

No reason for it to. Also I agree with the points above. Teams can get injuries so it allows them to get short term replacements.

Didn't Wenger actually say the transfer window should be all season long? That would be a bit hectic though imo.

Yes.
