Meanwhile the normally reliable Cook, 30, endured a prolonged slump with the bat before scoring his first Test hundred in nearly two years against the West Indies in May.“It was an incredibly tough time,” Cook said at a sponsor’s event at lord’s on Friday.“losing that Test series against Sri lanka and that fourth day at Headingley is as tough as it can get, so from where we have been if we did win the Ashes at The Oval that would be remarkable, and something I would be very proud of — it would be my best achievement.” he said.
