I think that what you're seeking to do is almost certainly impossible.
When websites were first invented, they were designed in just one format, using a fixed width for each page. That meant that someone who was trying to view a wide-page site on a small-width monitor would need to keep scrolling from side to side (or to reduce the size of the whole page) to be able to see all of its content. Conversely, someone with a wide-screen monitor, who was trying to view a narrow-page design, would see lots of blank space at either side of the page.
The problem of getting websites to fit different size monitors was largely overcome when web design technology was improved, so that pages would automatically shrink or expand to fit the width of any monitor.
However that didn't fully accommodate the needs of people using tablets and (especially) mobile phones. Shrinking a web page, which had been designed for a wide-screen monitor, to a size that would fit onto a mobile phone screen resulted in the text being far too small to read and links far too close together to tap on with any accuracy.
For a while, the problem of needing different versions of websites for desktop computers and mobile devices was partially solved by having different web addresses to be used by different devices. For example, TheAnswerbank's 'desktop PC address' was 'theanswerbank.co.uk', whereas it's 'mobile device address' was 'm.theanswerbank.co.uk', with that all-important 'm' at the front denoting the difference between the two.
That wasn't ideal though, as businesses wanted to be able to advertise just one web address for their companies, rather than having to tell people to use one address on a desktop PC but a slightly different one on a mobile phone. So 'responsive website design' was born.
Using 'responsive website design' requires a web designer to create different versions of a website for different devices but which can all share a common web address. It's possible to just use a two-version model but it's more common to use a three-version one. That means that a web designer has to create one version of a website for desktop PCs and laptops, a second one for tablet devices and a third one for mobile phones (with each of those designs being able to shrink or expand to fit different screen widths within a specific range).
The Answerbank, for example, is designed that way. It now only uses a single web address but, when someone visits that address, the device being used (such as a desktop PC or a mobile phone) identifies itself the The Answerbank's server, so that it's sent the correct version of the website to be used with that device. (The Answerbank looks very different on my mobile phone to how it looks on the laptop that I'm using as I'm typing right now. That's because my laptop and my mobile phone identify themselves whenever I visit the site).
So it is with Livesport.com. The web designer has created three different versions of the website. He or she has decided that the tablet version would be too crowded on a mobile phone screen, perhaps making it easy to tap on an incorrect link by mistake (or because the text would be too small for a mobile phone screen). So he/she has gone down the three-version path and created one version of the site for desktops and laptops, another for tablets and a third one for mobile phones.
I know of no way of tricking a mobile phone into thinking that it's a tablet (and thus declaring that to Livesport's servers in order to receive the tablet version of the site). Sorry!
