Manchester United boss David Moyes was in Lisbon yesterday on a scouting mission.

The Daily Mail says he attended Porto's Portugal Cup semi-final with Benfica at the Estadio da Luz.

Highly-rated centre-back Eliaquim Mangala and his Porto team-mate Jackson Martinez were the subject of his attention.

In addition, Moyes has also been alerted to the form of Benfica's on-loan left-back Guilherme Siqueira and was keen to see him in action.
