"It's frustrating, there's no doubt about that, but I know that we will get a positive response from the players."

Pearson insisted the situation had no impact on his players and their final preparations, and stated there was no ill-feeling towards Newcastle over the highly unusual incident.
"The players were all very relaxed about that," he added.

"There was no friction at all. Sometimes these things happen and you have got to deal with them."
