Simon Mignolet is now in his fourth season at Liverpool but the Belgian is still struggling to win over the supporters at Anfield.
The former Sunderland ‘keeper has made a series of mistakes at the club since his £9 million move in 2013 and was dropped by manager Jurgen Klopp for a short period during last season.
Since Mignolet has arrived, though, Liverpool have lacked a quality second-choice goalkeeper with the likes of Brad Jones and Adam Bogdan unable to provide him with serious competition.

Things have changed this season with the arrival of Loris Karius in a deal worth £4.7 million. The 23-year-old German arrived on Merseyside with a growing reputation having been voted the third best goalkeeper in the Bundesliga last season.
Karius missed the start of the campaign through a broken hand but has been given starts in Liverpool’s two previous Premier League matches against Hull City and Swansea City.

However, Karius didn’t look totally assured during the 2-1 victory against Swansea before the international break and some fans were asking whether he was ready to be the club's number one.
Therefore, days ahead of a massive clash against Manchester United at Anfield on Monday, there are many questions surrounding who Klopp will start in goal: Mignolet or Karius?
Well, Mignolet has named the shot-stopper he ‘expects’ to be between the sticks against Jose Mourinho’s side.
"I look at the positives and expect and hope to play against United," he told a news conference.
"I can still take confidence from my good start in the league. At Arsenal, Tottenham and against Leicester [City], I was important to the team with some good saves.
"I can just make sure I'm ready 100 per cent. Whether I play or not, nothing will change my preparation. It is not in my character to not give 100 per cent."
However, something that could sway the decision in Karius’ favour is the fact that he - along with the back-four of Nathaniel Clyne, Joel Matip, Dejan Lovren and James Milner - all stayed at Melwood during the international break and would have had plenty of time to work on their defensive organisation.
It’s certainly a big decision for Klopp to make in what is a massive match. Liverpool’s impressive start to the campaign sees them sitting in fourth after seven matches, just two points off table-toppers Manchester City.
Despite their decent start, Liverpool have already conceded 10 goals - seven more than Spurs - and that’s something they desperately need to address.
Whether it’s Mignolet or Karius who is responsible for helping to improve that record remains to be seen.
