Police searching for Jay Slater are set to endure a "laborious and consuming operation" as they prepare to scour fresh CCTV footage and security cameras.
The 19-year-old from Lancashire went missing eleven days ago in Tenerife after attending the NRG music festival with friends.
The Guardia Civil have combed through mountainous terrain and ravines in a bid to find Slater, with no evidence found so far.
In a fresh claim, The Mayor of Santiago del Teide said locals spotted the teenager watching the football tournament "on the coast".

Discussing the latest developments on GB News, journalist Nick Pisa said the claims made by the Mayor are "bizarre and confusing", and that police are "double checking everything" in the hopes of finding Slater.
Pisa revealed: "I managed to speak to the Mayor yesterday morning, and he was keen to clarify and clear up the situation.
"He'd spoken to some locals who had told him that they had heard that they had seen Jay drinking in bars in a resort called Los Gigantes, which is just about 10 to 15 miles further up the coast from Santiago del Teide."
Pisa also stressed that the Mayor has "no confirmation of this himself", and Spanish police are yet to confirm the claims.

Host Stephen Dixon questioned the "credence" of the claims made by locals and quizzed Pisa on how much the reports have been "removed and removed" before reaching the Mayor.

Pisa agreed, telling GB News: "You do have to wonder if it's all Chinese whispers, but I suppose at the end of the day they just have to rubber stamp and double check everything.
"Because if by a certain fluke that it is true and they then miss it and they've lost that clue, then obviously there would be all hell to pay for from the Spanish police."
In the latest line of inquiry following the claims, Pisa also revealed that teams are now "searching CCTV footage and security cameras" to clarify if the sightings are true.
Pisa continued: "They are searching the video cameras and the webcams that are in Santiago del Teide, and they've asked for the firms that operate and maintain those security cameras to hand over their video.
Nick Pisa claims the terrain where Slater is thought to have gone missing is a 'dramatic landscape'

"But obviously this is going to be a very laborious and time-consuming operation for them."
Turning the discussion to the ground search, host Ellie Costello asked Pisa what the nature of the terrain is where they are searching, and how no sign of Slater has been found after eleven days.
Pisa replied: "It is very rugged up there and the terrain is quite tough. It's covered with cacti and there's paths that lead off down to the sea.
"It's a good hour and a half trek from Maska down to the beach. I should say that the path actually has washed away a bit, apparently in a heavy storm a few years ago. So the path that he could possibly have been on doesn't actually reach the sea. But it's very dramatic landscape."
