Louis van Gaal has acknowledged Manchester United would like to sign more wingers, but he refused to discuss possible interest in Arjen Robben.

There have been reports of a £50 million transfer with Bayern Munich for Robben.

"When I answer the question you are writing 'open doors for Robben'. You will write things I didn't say," Van Gaal said prior to United's Champions League clash at home to PSV on Wednesday.

"I need more balance in my selection," he added. "We want a fast winger. We need to be where I want us to be."
