Rondon is yet to score for Newcastle but Benitez has been happy enough with the Venezuelan's contribution so far.
However, he thinks Newcastle fans are yet to see the best of the West Brom loanee, telling the Northern Echo: “He is doing well, but he can still improve. He will need match fitness, so we need to play games. He will continue training, and hopefully we will see the best of him in a few months.
“I think he is giving us something, but he can still improve. He came after an injury with West Brom and came late. Now, these games are very important for him."
