Jiménez would make sense if we use Rashford as the left-sided forward and Greenwood as the right-sided forward — and are convinced that they can score a high volume of goals on a consistent basis, so you can sacrifice some goals at the center forward position to accentuate their strengths. Both of them like to drift inwards and have a pop at goal, so they will benefit from the presence of a player who can bring them into play, press with intent, hold a high line if need be, knit things together...just make things easier for them and clear the traffic, so to speak.
A bit like Benzema at Madrid with Cristiano and Bale, or perhaps Mandzukić for Heynckes' Bayern with Müller, Robben, Ribéry and Kroos — albeit at a lower level because Jiménez is not as good as Benzema, and Rashford/Greenwood are not as good, or as productive, as those forwards/inverted-wingers, at least for now.
That being said, he is not the youngest player and might have already reached his highest level — what you see with Wolves is, in all likelihood, what you can expect in terms of peak performance — a good, and occasionally very good, but not great player. He's not suddenly going to develop a much better eye/appetite for goal — in that sense he's the antithesis of Chicharito: lovely all round play but not the most natural or opportunistic poacher.
To be honest, he seems to be a Pochettino style center-forward with regard to physical profile, touch of scrappiness as the focal point, ability to press from the front and so forth. Like Lambert at Southampton (top scorer under Mauricio but also assisted a club-high 10 goals). Or Kane (who is a more prolific scorer but still a good foil for the likes of Son and Alli). Or even Llorente for a wee bit.
