Stoke City manager Michael O'Neill has revealed how the club made painstaking inquiries before signing former Chelsea midfielder John Obi Mikel.
The 33-year-old was snapped up by the Championship side as a free agent on Monday on a one-year deal, having been without a club since parting ways with Turkish Super Lig side Trabzonspor in March.
The former Nigeria international made his name during his time at Stamford Bridge, where he spent 11 years and won a number of laurels, including the Premier League, Champions League and Europa League titles.
