It is believed that Boro's home games against Lazio (4th November) and Partizan Belgrade (15th December) will be shown live on Channel 5. Newcastle have been signed up by ITV2, to show their home games, so a Channel 5 screening would appear on the cards for Boro.
The other game, away to Villarreal (25th November) could be shown on either channel. With Newcastle playing away to Sochaux on the same evening, it's a toss up who who picks which match.
