I always try to find the best in the business when it comes to comparing two footballers. They have to be under a certain level of greatness.
So it will come as no surprise to you that I'm comparing David Seaman and Peter Schmeichel, who in their day were the best in the world at stopping a ball from crossing a thin white line.
From the Premier Leagues to the Champions League, the pair have played in them all.
So let's get down to it.
He arrived at the destination of Manchester in 1991 for the sum of £530,000 and went on to play eight years as the Red Devils goalkeeper.
In 1992 and 1993 he won the Worlds Best Goalkeeper Award after his performances for Manu and Denmark.
In total he won five Premier League trophies, three FA Cups, one League Cup and of course one Champions League trophy.
He was also part of the Dennmark side which won Euro 92.
His time at United went out with a bang when they won the treble.
David joined the Gunners in 1990 for £1.3 million and in his first season conceded only 18 goals.
In '93 he won the FA and League Cups and in '94 a European Cup Winners Cup trophy and in the same year he became England's number one goalkeeper and he held the position until 2002.
He got goalkeeper of the tournament award at Euro '96 and in '98 he won the double with Arsenal and in '02 he won the double again.
In his final game for Arsenal he won the '03 FA Cup and was said to have made one of the best saves off all time in the semi final against Sheffield United.
In total he made 325 appearances for the Gunners which can only be topped by Ray Parlour, and finally in '08 came 10th in the 50 greatest Gunners competition.
Well I hope that gets you guys voting and remember be as fair as you can, but I do recognize its Arsenal vs Manchester united.
Have fun casting your votes.
