O'Neill is finding a similar scenario with Porto defender Boswinga with his price also going up.

"Sometimes you have to go by what the other club says, but I am not panicking at all. Like everything else you always have to have a plan A, plan B, plan C, call it what you want.
"But the people I have pursued to begin with are worth pursuing. We have a number of opportunities and I would like to see those opportunities through to the end."
