West Ham boss Alan Curbishley is confident new signing Kieron Dyer will work well with his former Newcastle rival Lee Bowyer.
"I spoke to both players and have been assured that it was a one-off, and they both speak to each other regularly," said the manager.
"It was just two players desperate to do well; they were getting well beaten, and it just boiled over.
"Kieron's got to make up for a bit of lost time, and I hope he does. We're delighted to have him on board."
