 UBS and Morgan Stanley are expected to organise the lucrative listing of Vodafones European towers unit - a deal that could value the entire business at up to 16 billion euros 18 billion, sources familiar with the matter said. The two banks boast a close relationship with Vodafone and both pitched to become joint global coordinators in the listing, which is expected early next year, the sources said. Goldman Sachs has also pitched for a top job in the initial public offering IPO and hopes to be in the driving seat, they said.
