Superstars always color matches and help their team win games in times of difficult games. And when they leave there is always something to miss about them, the fan love, fans switching clubs, and most important the team losing top notch performance. Recently, Marquinhos made a statement that he
misses the days of Mbappe in PSG. He's sure that their draw wouldn't have happened in the watch of a no "9" like him. Also PSG fans would feel the absence of Messi and Neymar's brilliant skills. On the other hand, Manchester United also should be missing those moments of CR7.
What is no longer there in your club after a certain key player was transferred?
When I read this topic title the first scenario that came to mind I'm Mbappe and Benzema and CR7 all this are top players that their departure from their club's cost alot of set back and space that no replacement can be made for a long time, so for sure when a big player leave a team, the reversed effect is so negatively felt and for a long time, and that is why some time, clubs do everything possible to keep they old time and experienced player's because if you lose them to other club's, it then means that you lost your investment and another team will be enjoying the fruit of your labor.
If the player have already spent more than two seasons, that is approximately around tow to three year in the club and haven't won football awards which helps exposed them and they fames, it becomes necessary to retain and cherish such a player, because having them in your team is a big added advantage and a motivation should be place before them some that other club's will not temp them which not many can walk away from, let say in the areas of player's payment and treatment when they sustain injuries.
