The 23-year-old defender has penned a five-year deal with the Europa League finalists, after being persuaded to join by compatriot Pablo Aimar

Benfica have completed the signing of Lisandro Lopez from Argentina outfit Arsenal de Sarandi.

The 23-year-old defender has signed a five-year deal for an undisclosed fee, with his contract believed to include a €35 million buy-out clause.

Lopez has frequently been overlooked for Argentina duty by coach Alejandro Sabella despite impressive performances for Arsenal, and he admitted his desire to break into the Albiceleste coach’s plans was a significant factor in his decision to move.

“I have chosen Benfica because they are one of the biggest clubs in Europe and many Argentines have succeeded here,” Lopez told Benfica’s official website.

“I am anxious to start. If I play well here I may get a chance in my country’s national team.”

Lopez revealed he had been persuaded to join the Europa League finalists after compatriot Pablo Aimar had extolled the benefits of life in the Portuguese capital.

“He said Lisbon was beautiful and Benfica was huge and magical. He told me to enjoy my stay here to the full,” Lopez added.

Lopez becomes Benfica’s seventh signing of a busy summer so far, following Stefan Mitrovic, Lazar Markovic, Miralem Sulejmani, Filip Djuricic and Uros Matic – as well as central defender Steven Vitoria.

Lopez’s arrival could cast further doubt over the future of Ezequiel Garay, who has been linked with a move to Manchester United this summer.

London, October 19 (ANI): Former football stars have ousted the incredible diet secrets of their sports fraternity. Caffeine tablets and sleeping pills in tandem with energy drinks, bars, protein shakes and even seemingly unhealthy dishes like banoffee pie and pizza are fuelling the players in the high-speed world of modern football.

Glen Johnson opened the window into the highs and lows of the international game, revealing how England’s players were given caffeine tablets to get pumped up for the delayed World Cup qualifier against Poland in midweek and that some then needed sleeping pills to bring them back down again when the first match was postponed.

After Liverpool full-back, Johnson provided an insight into football’s pill-popping world, his former international team-mate Rio Ferdinand expressed his surprise that people were surprised.

Arsenal boss Arsene Wenger has been at the vanguard of the revolution in players’ diets over the past decade and a favourite among his players is banoffee pie – the bananas and sugar contained in the gooey treat boost energy levels.

At another Premier League club, pizzas are always on the post-match menu, with boxes arriving in the dressing room for players to munch after matches in an effort to load up with carbs and quickly regain energy.

Pasta is a favourite the night before games, although the notion of players needing pills to get hyped up for an England game may seem strange to fans.

“It was a kinda crazy couple of days – preparing to play, then living exactly the same day the next day,” the Mirror quoted Johnson as saying.

“It’s been a bit strange and I don’t think anyone has had to go through that before – but it’s part and parcel of being a professional.

“It’s obviously not done you any favours. For example, a lot of the lads take Pro Plus (caffeine) tablets before the game and we all took that for the (first) game, then the game is off and no one can sleep,” he said.

Ferdinand admitted that he has problems sleeping after games.

“What’s all the fuss with caffeine/sleeping tablets?? Players have used them for yrs before + after games without any fuss,” he tweeted.

Everton’s ex-England regular Phil Neville tweeted “Throughout my career players have taken sleeping pills night be4 game and caffeine tablets day of game never been a problem in media be4”, and later deleted it.

Caffeine – or at least a certain amount of it – was on the World Anti Doping Agency’s banned list until 2004, so athletes had to watch how many cans of caffeine-loaded energy drink Red Bull they drank before a race.

One Premier League physio claimed on Thursday, that caffeine pills are available in every dressing room but would never be forced on players.

Players talk about caffeine not being used for energy but more to help with focus.

Herbal sleeping pills, in contrast, are used to try to take the edge off players who are high on adrenalin – particularly after games.

UK Athletics is believed to have a rule that no athlete should use sleeping pills within 48 hours of a race.

Former athletes still remember one sprinter going into a Championship in the 1990s hoping to break the 20-second barrier in the 200m. He could not sleep and persuaded the reluctant team doctor to give him a sleeping pill the night before his big race.

Instead of cracking 20 seconds, he came home in over 21.5 seconds.

One well known British athlete was known for eating small doses of rat poison as it contained the stimulant strychnine.

Scientists are split over whether caffeine makes a real impact when players use it.

One athlete said that he has been advised never to drink more than 12 cappuccinos, as it could cause a suspicious caffeine reading. But other experts insist it would not boost performance.

Caffeine is not on the World Anti-Doping Agency’s banned list, but Dr Neil Chester, a researcher at Liverpool John Moores University, says it could potentially be more effective than some banned substances.

“Scientific literature unquestionably backs up the idea that caffeine is a performance enhancer,” Chester said.

“It certainly seems to be more effective than something like ephedrine, which is banned by WADA.

“There is, without doubt, a moral and ethical issue surrounding caffeine’s misuse in sport,” he added. (ANI)
