Liverpool lead FC Porto 5-0 going into the second leg of their Champions League last 16 tie at Anfield on Tuesday night, and Reds fans are all making the same surprise claim about goalkeepers Loris Karius and Simon Mignolet.

The former has established himself as the Merseyside outfit's first-choice stopper between the sticks in recent months, and he kept a clean sheet as his team beat Newcastle United 2-0 at home in the Premier League on Saturday.

With their progression to the quarter-finals of the Champions League looking to be all but guaranteed, manager Jurgen Klopp will be tempted to give some of his fringe players – of which Mignolet is now one – starts, but the Anfield faithful certainly aren't keen on the Belgian replacing Karius on his 30th birthday, even with the great position the club finds themselves in ahead of the match.

Liverpool supporters were quick to have their say on the situation via social media, and while one said "I hope Karius continues in goal", another said they would "be livid if Mignolet starts tonight".
