Its amazing how players fall of career trajectory if they move to a different leagues take Tomori and Abraham, who seemed bright young England hopefuls in the PL and seem just have fallen of any radar playing in Serie A. That said you have Bellingham and Sancho, who got recognition with moves away - though they were dropping shapes in the CL.
The Dutch league wouldn't be great, you can get talented players there, but as a % of players they would be in the lower sample.
Why i wouldn't sell him to PSV is that their model is all about investing, improving and selling for a higher fee - they obviously see an appreciation in Jarrod as an asset, id prefer if we cultivated that - even if we are to sell at some stage.
