Watford manager Gianfranco Zola has admitted that it will be "very tough" for his side to gain automatic promotion from the Championship after their defeat at Peterborough United.

The Hornets were beaten 3-2 by the strugglers at London Road on Saturday to leave them six points off second-placed Hull City.

"It was a bad day for us and getting automatic promotion will now be very tough, but we will keep on fighting as you never know what can happen in football," Zola told Sky Sports News.

"We paid the price for making some stupid mistakes and also for a couple of decisions that the referee could have made in our favour."

Watford continue their campaign on Tuesday when they travel to Millwall.
