West Ham United co-owner David Sullivan has no doubts about the quality of Enner Valencia.
The Hammer have spent big on the Premier League rookie from Mexico's Pachuca.
Sullivan told whufc.com: "The player we've spent the most money on, Enner Valencia, is our big summer signing and he is about two or three weeks away from being able to play, because he was at the World Cup.
"He's now in full training but I think the earliest he'll play is in the Capital One Cup match, so it'll be exciting for people to see him make his debut in that match.
"We were looking at Enner from before the World Cup, when Ecuador played Australia at Crystal Palace and he was the leading goalscorer in Mexico.
"Goalscorers are goalscorers and his goals per game for Ecuador since he's been playing centre forward is very high. He scored more goals at the World Cup than the England football team, he was in the top ten goalscorers of the tournament, even though his team got eliminated at the second stage, so he's a player with potential."
