West Ham boss Slaven Bilic says it is difficult for both Andy Carroll and Javier Hernandez up front together.

"It is possible," Bilic said when asked about playing the pair up front together.

"I am thinking about them the most but it is hard to have them both in their natural positions.

"It is hard to do that and then have three at the back, then with Antonio and Arnautovic, it is almost impossible."
