The Gunners star has agreed personal terms with the Red Devils and Haughton believes the Premier League pair just need to agree a fee, believed to be around £11million, for the Belgian. Speaking to the Weekend Sports Breakfast show, he said: "Arsenal could let Thomas Vermaelen move on. He’s only got one year left on his contract. "The deal would cost Manchester United around £10-11million. My understanding is that personal terms have been agreed with Manchester United, the clubs just need to agree a transfer fee."
