We had Mata arguably the leagues best #10 and we finished 6th and 3rd and we're no where near winning the Premier League.. Oscar gives us balance and while his playmaking abilities are inconsistent they are getting better.. Still only 22 and most AM you are looking to replace him with have 2-3 years age difference and when they were Oscars age you barely heard about them... Patience is key with young Oscar but everyone has this Fifa /FM idea that if you put world's best in form players on a team you will win real life doesn't work that way unfortunately
