I was once told by an English teacher that the construction "including" should be preferred over that of "such as" when developing an idea like the following:

English Football league teams including Manchester United, Liverpool, Arsenal, Chelsea, Tottenham Hotspur, Manchester City are quietly gearing for the summit of the European footbal hierarchy.

What's the outlook on this?
I'd say there's not much difference. They both mean that you are providing examples of the kind of teams you have in mind but not an exhaustive list of such teams.
There's a very slight difference in use.

'Such as' is an alternative for 'for example', so the specific teams named in the list are just examples - a random selection from among those that could have been listed*.

If you use 'including', you are drawing the reader's attention to some specific examples. You want the reader to understand that these particular teams are among those doing whatever it is. Your list isn't so random. In the example you use, I think the teams listed are specifically chosen (they are the the teams that have a chance of winning the European Cup maybe? ) rather than just random football teams, so 'including' is better.

*If your list is there to illustrate the point that you are making, then 'such as' is more appropriate - "Some English villages have funny names, such as Middle Wallop, Sixpenny Handley, and Little Snoring."
