#3 Sergio Romero
When Manchester United announced the signing of goalkeeper Sergio Romero in the summer of 2015, many assumed the Argentinian would become the club's number one goal stopper due to many months of speculation of David De Gea linked to Real Madrid.
However, of course, De Gea still remains United's no. 1 three years on, and looks to be staying at Old Trafford for a while, leaving Romero sitting in the shadows.
Before Romero signed with United, many will remember the Argentine for making a number of spectacular saves in a penalty shootout against the Netherlands which helped Argentina reach the final of the 2014 World Cup in Brazil.
With Romero's talent being wasted on the United bench, there have been rumours of the 30-year-old looking for ways out of the Theatre of Dreams. If these rumours were to be true, could you really blame Romero for searching for other opportunities elsewhere with the potential of being given more game time?
Romero is much better than being a team's no. 2 goalkeeper.
