Tottenham winger Erik Lamela is backing former club AS Roma in today's derby against Lazio.

Lamela left Roma last month.

"I will definitely watch the Derby," Spurs star Lamela told La Gazzetta dello Sport.

"I wish all the best to all my teammates at Roma and I hope they win on Sunday. This season the club has formed a really strong team and I am sure the best is yet to come for the Giallorossi."
