#3 Expectations
To whom much is given, much is expected. Neymar's world record move to Paris Saint Germain in the summer came with a lot of expectations. Afterall, no club would want to splash that huge fee on a player and not expect him to justify his worth.
If you take a clinical look at the Brazilian this season, however, you will realize that he has fallen below his expectations. He might have helped the French club to reclaim the Ligue 1 title, but his major task was to lead them to Champions League triumph, which he clearly failed to do. Moreover, he was also expected to overtake both Lionel Messi and Cristiano Ronaldo in the Ballon d'Or race, but he doesn't look like he is even next to them yet.
When Liverpool signed Salah in the summer, the club couldn't have imagined what fortune the winger would bring to the club. At his signing, there were very little expectations before him, but he has surpassed all and has reached the highest level of performance in the world.
The top scorer in the Premier League and the PFA Player Of The Year - these are things that the Liverpool owners couldn't have imagined he would achieve when they paid his price in the summer.
He might not have won a trophy yet, but his impact on the Merseyside club this year is quite unimaginable. He has kept the club in the top-4, as well as putting them on course for a sixth Champions League triumph.
