Emmanuel Adebayor is handed the lone striker role as Tottenham look to book their place in the knockout stages of the Europa League with victory over Lazio at the Stadio Olimpico. Andre Villas-Boas makes four changes from the team that lost 5-2 to Arsenal on Saturday, with Gylfi Sigurdsson, Clint Dempsey, Steven Caulker and young midfielder Tom Carroll all handed starting berths.
Good evening everyone and welcome to the Stadio Olimpico for the Europa League Group J clash between Lazio and Tottenham. Spurs could qualify with a win tonight, but only in Panathinaikos can overcome Maribor later on this evening.
