BURNLEY boss Sean Dyche has warned that every position is "up for grabs"  ahead of facing West Ham today.

The Clarets are determined to bounce back after three successive defeats the most recent coming against a strong Sheffield United side last weekend.

 Dyche feels competition is a fierce for a place in the starting XI, that coming into sharper focus after the 3-0 reverse at Bramall Lane.

"Shirts are always up for grabs but if you have a tough result and a tough performance then it is fair to say it enhances that fact," he said.

“I mentioned about the competitive group that we have and that has been on display this week. People want the shirt and want to go and play.

“The open mindedness comes flowing back in because it is not what we expected or wanted so it keeps everyone alive.”

Despite the disappointment of last Saturday's defeat, Dyche insists he is still looking to the positives, remaining optimistic about the season ahead.

 “We have had a good start to the season and I don't think one result makes it not a good start, particularly when you compare where we are this season to where we were last season," the Clarets boss said.

Burnley and West Ham will be equally as desperate to leave Turf Moor with three points, this weekend's visitors without a win in five.

“I can only imagine from the outside-in that their manager (Manuel Pellegrini) is scratching his head sometimes because they certainly have talent and are a good side when they are all on it and play well," Dyche said.

“They have had a couple of down days and that can happen. We are all searching for consistency in performance and they are probably trying to find their consistency.

“It is not for me to really worry about them other than to make the players aware of some of their threats but equally some of the ways we can affect them."
