Everton boss David Moyes is pleased with the deadline day deals.
"We are going to wait and see with the new boys," said Moyes. "Royston is explosive and hopefully he'll give us a bit of that pace. It's something new for him to come to England but we will give him time. We needed to try and find something extra for us.
Stracqualursi arrives having topped the scoring charts in the Argentine Primera Division, and his new manager is optimistic he can continue that rich goalscoring vein in England.
"It happened very late and there was not enough time."
