Levi has amassed 632 runs in 10 matches for Northamptonshire at an average of 42.13. He boasts the third-best average for the English county.
The hard-hitting opener revealed that refining small technical things were the key to his transformation after a slow start.
“I did a lot of work with Owais Shah (a former England player) who helped me massively to figure out game plans and strategy. The Duke Ball and the wickets here made for a testing time,” he said.
Kleinveldt has taken 47 wickets in 10 matches at a sensational strike-rate of 41.9, including four five-wicket hauls.
Levi said the 168 he scored against Essex in the first-innings of their first-class match, followed by an unbeaten half-century in the second innings, proved he can bat for long periods and score big hundreds.
“Pitches will always be sporting here (in the United Kingdom) along with the Duke Ball and it makes life interesting. But if you grind it out, it is easier to score later when the balls become older on rapid outfields,” said Levi.
Levi, who holds a United Kingdom-passport, is registered under the Kolpak-ruling for Northamptonshire, while Kleinveldt is the county’s overseas player.
The fact that Levi is a Kolpak-player, makes him ineligible for South Africa, despite his superb limited-overs season for the Cape Cobras in which he slammed 350 Momentum One Day Cup runs at an average of 38.88 in the 2014/2015-season, and 392 Ram Slam T20 Cup-runs at an average of 39.20.
The belligerent hitter said his goals are still to win matches and trophies for the Cobras and to enjoy Cape Town. His aim for Northamptonshire is to squeeze his way to 900 first-class runs in the last few championship games.
Asked about the upcoming series between South Africa and England (Newlands will host the test from 2nd January against England), Levi said: “I think it is going to be an interesting series.
“They are on a high after winning the Ashes series (against Australia), but haven’t done as well in foreign conditions.
“They have got some new blood in their squad and are paying a new style of cricket. It’s going to be a great series regardless of the outcome,” he added.
