The Numbers Behind Aston Villa's Bet on Nicolas Jackson
Unai Emery paid a club-record fee to replace Ollie Watkins with a striker whose Chelsea spell was defined by missed chances — but the underlying data always pointed to quality.
Aston Villa spent a club-record £65 million on Nicolas Jackson this summer, bringing him in to replace Ollie Watkins just two days before Watkins's £50 million move to Al Hilal was finalised, according to The Analyst (Opta).
The timing mattered. Watkins had scored 86 non-penalty Premier League goals since the start of 2020-21, a tally only six players in the top five European leagues bettered over that period, The Analyst reports. At 30, though, and with Villa in a rebuilding phase, the sale made sense for both parties.
Unai Emery had been reluctant to let him go. "I don't want to sell [Watkins], but it can change because if it's a good option for him and the club and I can replace him in the squad," Emery said, as quoted by The Analyst.
Villa already had a replacement lined up in Jackson, a player Emery had previously worked with at Villarreal.
Why Chelsea never got the best of him
Jackson's two seasons at Stamford Bridge, followed by a loan at Bayern Munich in 2025-26 as understudy to Harry Kane, left his reputation in England far from secure. But the physical and technical tools were always there.
Built on pace and a relentless work rate despite a slight frame, and standing 6ft 2in, Jackson could be a genuine threat in the air as well as in transition. His technical polish traces back to a childhood playing street football and a formative career spent out wide as a winger, per The Analyst.
Crucially, he was consistently finding dangerous positions. Before this season, Jackson averaged 0.57 non-penalty expected goals per 90 minutes in league football going back to the start of his Chelsea career — the eighth-best figure among 654 outfield players to log at least 5,000 minutes across the top five leagues in that span, The Analyst's data shows.
The finishing problem that followed him
The underlying numbers never translated consistently into goals. Across 2023-24 and 2024-25, only two players in Europe's top five leagues underperformed their non-penalty xG by a wider margin than Jackson's -7.0, according to The Analyst.
His 31.0 non-penalty xG over those two seasons was the eighth-highest total in that period — marginally ahead of Watkins's 30.7. Yet where Watkins converted his chances into 33 goals, Jackson managed only 24 from a near-identical underlying total.
Examples from those seasons illustrate the pattern: against Brentford, he burst beyond two centre-backs into a clear sight of goal but let the covering defender block a tame finish; against Arsenal, he skipped past a marker only to drag his effort into the side-netting with the keeper beaten, The Analyst notes.
Across those two campaigns Jackson was presented with 61 Opta-defined big chances in the Premier League and converted just 29.5% of them, the 10th-worst rate among the 90 players to receive at least 30 such opportunities, per The Analyst's figures.
Why Villa are backing the underlying data
The gap between Jackson's chance quality and his conversion is the central tension in his profile. He generated shots and positions at a rate that put him among the best strikers in Europe by underlying output, yet repeatedly failed to finish in the moments that mattered most.
Some context softens the earlier struggles: Jackson arrived at Chelsea just 10 days after turning 22, with only a single season of top-flight experience behind him, The Analyst points out.
Villa's calculation, in effect, is that a forward who was already among the best in Europe at finding scoring positions and winning aerial and transitional duels can close the finishing gap with time, coaching continuity under a manager who already knows him, and a reduced burden after sitting behind Kane at Bayern.
It remains early in his Villa career to say the doubts are fully answered, but the signs Emery and the club were looking for are visible in the underlying numbers that always separated Jackson's talent from his output at Chelsea.
