Reminder - he's only 18 (19 on Monday). Sancho has 9 goals and 17 assists this season. He's been at least partly responsible for 26 goals therefore and the season isn't yet over. That's more than anyone in our squad.
To put that into context, in Cristiano Ronaldo's equivalent age season at United, he got 6 goals and 9 assists (9 goals and 10 assists the season he turned 20, 12 goals, 9 assists the one he turned 21, 23 goals and 20 assists when he turned 22). In Lionel Messi's equivalent age season, he scored 8 and assisted 4 (17 goals and 3 assists the season he turned 20, 16 goals and 15 assists the one he turned 21).
Albeit the Bundesliga is different to La Liga and the Premier League, it took Ronaldo and Messi til the seasons they turned 22 and 21 respectively to be responsible for more goals than Sancho in the season he turns 19. Not bad going.
I'm not saying he has the potential of Messi and Ronaldo but his young career has started spectacularly. He's English and appears to have all the tools to be an elite player for many years - he's fast, a good passer, intelligent in his final product, skilful, adopts good positions, hard working and motivated. There's some criticism of his first touch based on tonight but I've seen a lot of him and he's usually excellent in that regard. Don't forget it was his first competitive England start tonight so it may be nerves. Many of us have seen Sancho before he signed for Dortmund; especially in the England U17 World Cup winning side where he was outstanding.
The boy's a serious, serious talent. Yes, signing him for £100m plus (try £140m plus) is a gamble. But would you have turned down Mbappe after his breakthrough season at Monaco? Top tier talent is worth investing in. Even if he maintains his current level and doesn't develop, he'd still be a useful addition to us but all signs point to him getting much, much better.
