THE impact of Wanderers' involvement in the UEFA Cup has already had an effect on next season's fixture list.

The away games against derby rivals Manchester City and Wigan Athletic, originally scheduled as Saturday fixtures - September 17 and October 1 respectively - have both been put back 24 hours.

And more re-arrangements will follow, if Wanderers clear their first European hurdle and qualify for the group stages.

When UEFA Cup ties are played on Thursday evenings, competing clubs are not asked to play their next Premier League fixtures until Sunday at the earliest.

But the busy schedule, which Sam Allardyce fears will put a serious strain on his squad, can have an even greater impact once domestic cup competitions come into play.

Should Wanderers reach the group stage of the UEFA Cup, the first set of games is scheduled for Thursday, October 20. The Premiership game at home to West Brom would then have to be put back to the following Sunday, after which the Whites would have only two days to recover before opening their Carling Cup programme with a third round tie on Wednesday, October 26 - three games, in three competitions, in seven days, with no let-up in November or December.

If they were to match Middlesbrough's successful run on their European debut last season, the cramming would start all over again in February when the FA Cup could come into play.

It means Wanderers fans need to be aware that more Premiership fixtures listed for Saturdays will have to be rescheduled the more success the Whites have in Europe, regardless of Premiership matches selected for live TV screening.
