2017 has been a whirlwind year for both football and its fans alike. We've been privileged to witness some truly spectacular results, transfers, and even goals. In the process, we've witnessed records tumble, be rewritten and the rulebook redefined.Most leagues have closed their doors for the winter break midway through the season, now would be an appropriate time to review some of the headline events of the game that have happened in the last 12 months.It must also be stated that these highlights are placed in no particular order or rank; these have been chosen based mostly on their significance and impact on the beautiful game we know and love.#1 Real Madrid Winning La Duodécima Los Merengues celebrating their 12th UCL title and 2nd in a rowOne could argue that no team has enjoyed a more prosperous year than Real Madrid. Whilst Real have broken more than one record in the process of picking up 5 trophies over the past year, their most notable achievement (arguably) would have to be their 12th Champions League crown.Their unmatched success in Europe's elite competition puts them five ahead of second-placed AC Milan (with seven titles) in the list of all-time winners. Enroute to La Duodécima, Real had to overcome the likes of Napoli, Atletico Madrid, and Bayern Munich. In the final against Juventus, Madrid produced a masterclass to secure the trophy by winning 4-1 with Cristiano Ronaldo securing a brace.The win made them the first team to successfully defend their title in the Champions League era and the first to do it since Arrigo Sacchi's AC Milan side managed it back in 1989 and1990.
