Kel Varnsen Partey is amongst the best in the world and was playing like the worlds best DM before World Cup.
But selling him now for a reasonable fee would actually be good squad hygiene. We can rebuild midfield and position ourselves for the next 5+ years. Given his injury record (never more than 22 starts in 3 seasons), and from decline last season, a sale is a good consideration. We cannot depend on players who cannot be relied on to be present or at their peak. That’s how we died with RVP, Wilshere, Ramsey etc., back in the day
