Wigan Athletic boss Roberto Martinez was delighted with Ryo Miyaichi's performance in their Capital One Cup win over West Ham United.

Miyaichi is on-loan at Wigan from Arsenal.

"I was very pleased with his performance. I don't think he missed anything," Martinez said.

"He built a very good relationship with Ronnie Stam and Maynor Figueroa, the link up play with Mauro Boselli looked really natural too.

"I saw him as a real threat and he gives us a lot of penetration. Overall his contribution was very good and he is a player that is growing.

"He is still a young man but he will be a very important player for us potentially.

"He can play on the right or the left, he is decisive in one-on-ones and he is a really good outlet.

"He is one of those players who you really want to pay to watch. I was very pleased with his work-rate and his understanding."
