Draw According to UEFA:
One team from each pot will be drawn to form a group, however, no two teams from the same country can be in a group. So Boro can't be in the same group as Newcastle, Rangers can't be in the same group as Hearts etc.
Once the eight groups have been drawn a computer draw will determine the fixture scehdule, taking into account stadium clashes and climatic conditions (it may not be possible to play in some countries in mid-December).
Draw According to MFC (and other soucres)
One team from each pot will be drawn to form a group, as above.
Once the groups have been drawn each team is given a letter; A, B, C, D or E which determines their schedule of games. Apparently Boro have been given a B (how, when, where & why, no one knows).
Then, the schedule for matches is as follows:
Matchday 1 (21st October) D v B & E v A (C not playing)
Matchday 2 (4th November) B v E & C v D (A not playing)
Matchday 3 (25th November) A v B & E v C (D not playing)
Matchday 4 (1st/2nd December) C v A & D v E (B not playing)
Matchday 5 (15th/16th December) A v D & B v C (E not playing)
So, if Boro are a B we will be away on 21st October and 25th November, while we will be at home on 4th November and 15th/16th December.
How this schedule takes into account stadium clashes and climatic conditions is unclear.
Still unsure, well you'll just have to wait and see how it all unfolds tomorrow. Don't forget the draw is live on British Eurosport starting at 11am BST.
