The West Bromwich Albion striker says he might have done more.
The 26-year-old enjoyed a decent first season in the Premier League following a £13 million switch from Zenit St Petersburg last summer.
He netted nine times in England's top flight, along with one in the FA Cup, but the Venezuela international managed some 39 appearances in all competitions.
Given his lofty transfer fee, it is an okay return for the money spent on him, but Rondon himself hints that he might have perhaps scored more.
"[It was] a bittersweet experience because I was able to finish with ten goals in the season," Rondon said, via the Birmingham Mail.
"It may have been more but it was my first season in England and it's a complicated league. It was a learning season, although I am happy because the team's objective of maintaining our Premier League status was fulfilled."
It was a pretty bang average season for West Brom on the whole, with Tony Pulis's side finishing 14th in the Premier League.
Their cause was not helped by the fact Saido Berahino failed miserably to emulate his 20-goal season from the 2014-15 campaign.
If and when Berahino leaves, the goalscoring burden will rest more prominently on Rondon's shoulders and the South American will hope to step up.
