The Venezuelan striker joined the Baggies from Zenit St. Petersburg in the summer transfer window, and there was a great deal of excitement around his arrival at the Hawthorns.
However, it took Rondon a while to get to grips with Premier League football – with his initial performances off the pace.
Rondon now has scored two goals in his last three matches, though, and Le Tissier believes that the powerful forward is starting to show his class.
“He does look a threat,” he said. “It’s taken him a few weeks to find his feet, but Tony Pulis has spoken very highly of him. He always said he was seeing things in training that he felt that this boy would make an impression in the Premier League.
“He certainly seems to be doing it right now.”
Part of the reason for Rondon’s initial struggles has been attributed to his international commitments, which disrupted his progress.
The 26-year-old has been forced to do a lot of travelling between South America and England, making his transition period all the more difficult.
Rondon will be hoping to build on his recent displays when the Baggies next return to action, though, with the Midlands outfit’s next match coming against title-chasing Arsenal.
