Hoddle wrote in the Mail on Sunday: "When you look at the most astute transfers, Chelsea's signing of Nemanja Matic last January and Alex Song's return to English football in the summer are right up there. But Song isn't even the best buy at his club - that honour falls on Diafra Sakho and Enner Valencia.
"That's a huge compliment to Sam Allardyce. Real football people wouldn't doubt him but he has gone from being under pressure at West Ham, with the fans discontented, to having engineered their best start in the Premier League and much of it is down to clever recruitment. There aren't many undiscovered gems any more but plucking a player like Sakho from Metz in the French second division is as close as you get. Valencia shone in the World Cup but there can always be a risk buying on the back of a good tournament - but West Ham had clearly done their homework.
"West Ham get the ball down and play with those two, hitting teams on the break; when Andy Carroll comes in, they go a bit more direct. They have two ways to play now - Valencia and Sakho have added a new dimension to their game."
