Rondon arrived at Goodison Park on deadline day of the summer transfer window, linking up with Benitez for a third time in his career after spells together at Newcastle United and Dalian Professional.
The 32-year-old has now started the last five Premier League games on the trot for Everton with first choice hitman Dominic Calvert-Lewin sidelined with an injury.
Rondon is yet to make any direct attacking contributions for the Toffees and had another underwhelming outing at the weekend in their 5-2 home loss to Watford, which is a massive issue when he is the club’s main number 9, according to ex-Everton star Ball.
The former full-back insists that Rondon has not been able to do anything that Everton strikers are expected to do so far into his stint as he has time and time again failed to make his mark in the game.
“I’ve given Salomon Rondon the benefit of the doubt because he’s been playing catch-up fitness wise and has been playing in a lesser league but he’s got to do something”, Ball wrote in his Liverpool Echo column.
“You’ve got to make your mark in the game.
“We’ve had lots of different types of strikers at Everton, some would run the channels and make it difficult while others like Duncan Ferguson and Paul Rideout wouldn’t, but they would dominate the centre-half and bring others into play so you can keep possession.
“Rondon is not giving us that outlet at all.
“I didn’t see our striker create one chance. He didn’t do anything.
“That’s a massive issue when your main number 9 is not having any opportunities on goal, there’s a problem there.”
Everton received an injury boost last weekend with Richarlison making his return from a knee problem, while Calvert-Lewin remains on the road to recovery from a broken toe and a quadriceps injury.
