Rafael Benitez returns to the UK as his Napoli side take on Swansea in the first leg of their Europa League last-32 clash (kick-off 8.05pm).The former Liverpool and Chelsea boss is bidding to become the first manager to win the competition with three different clubs.After success with Valencia in the UEFA Cup in 2004, the Spaniard secured a dramatic victory in what was his final game as Chelsea boss in the Blues' success over Benfica in Amsterdam last May.
