By Jaya Narain Last updated at 12:32 AM on 14th October 2011 With his shirt stained with blood and a nasty gash above his left eye, Paul Merson makes his way home after a stay in hospital. The former England footballer said he was lucky to be alive following his 70mph motor- way smash in the early hours  of Wednesday. But now Merson – whose addictions to gambling, drugs and alcohol drove him to the brink of suicide – is at the centre of a police investigation after being arrested on suspicion of drink-driving. Sky Sports pundit Paul Merson was pictured leaving Warwick Hospital yesterday after sustaining cuts to his head following a crash on the M40
