Man United confirm Martial signing

Manchester United on Tuesday confirmed the signing of 19-year-old French striker Anthony Martial from Monaco on a four-year contract with an option for a further year.

"Manchester United is delighted to announce that Anthony Martial has completed his transfer from AS Monaco," the club announced on their website.

United did not disclose the transfer fee, but British reports said it was £36 million ($55.1 million, 49 million euros) -- a record for a teenage player -- with reports in France suggesting it could rise to 80 million euros.

"I am so excited to be joining Manchester United," said Martial. "I have enjoyed my time at AS Monaco and I would like to thank them and the fans for everything they have done for me."
