No disrespect Tommy, as I’m a big fan of your work on here, but not sure a young Keane is a fair comparison for Parrott.
Had the joy of watching Keane in his first season, including a Keane & Bull double in our first live game which was like watching the rebirth of Jesus for our family. However, Keane benefitted greatly from the experience of Bull, Goodman & Freedman upfront, a supply line of Froggatt & Simpson & quality players like Murray, Richards & Curle at the back, so we were infinitely better than what looks an extremely turgid Millwall team.
That said his impact was astounding with two on his debut and top scorer with 11 in the league (surprisingly low given the calibre of striker, although McGhee rotated players), however as a striker he was a once in a century type player, let alone once in a generation for Ireland.
From what I’ve seen of Parrott, he seems a different type of Kane like player with a taller physique who possibly needs to grow into his frame (Drogba took until his mid-20’s), whereas Keane had that elusive low centre of gravity running from deep. That said, Keane’s attitude and confidence was impeccable, so if Parrott’s attitude is poor, maybe this is the humbling he needs to bring him down to earth and focus his attention.
