Neil Lennon resigned
Many footballers and organisations worldwide have taken to social media to express their condolences for Neil; including Liverpool club captain Steven Gerrard and Alan Shearer
All those in football will agree that this is an extremely sad day, however questions are already underway as to who will take over at the helm, with Celtic's official twitter account leading the speculation.
Many betting companies have also raced to produce the best odds for those looking to gamble on who will takeover at Scotland's biggest side, with Sky Bet widely being considered to be offering the best odds. They state that Fabio Capello is currently the favourite at 5/1 while they also give chances to Roberto Di Matteo, Michael Laudrup and Ernesto Valverde with odds of 9/1, 15/1 and 44/1 respectively.
