Is being a keeper the hardest position on the field?
Neil Lennon, talking of his keeper Fraser Forster, said: "Good goalkeepers are hard to find and we feel as if he has great potential to go on and become a great goalkeeper."
It led me to ponder the question, is being a keeper the hardest position on the field?
I would argue 'yes'.
The vast bulk of managers, players, fans and even journalists, have some experience, at whatever level, of playing football.
But very few have experience between the posts.

Scarcely a manager in Scotland has been a goalkeeper, hence the reason for employing specialist goalie coaches.
So who can truly judge, with genuine expertise, the man for whom one mistake between the sticks can be fatal?
Dunfermline keeper Chris Smith has had a bad run in recent weeks, but the very position he plays in has amplified his errors.
Strikers miss chances, midfielders miss passes and defenders miss tackles, but very few of those will have the instant and dramatically game-changing effects of a goalkeeping howler.
It goes without saying that good keepers need athletic flexibility, bravery, the ability to judge angles and great reflexes.
All of them, though, require more than anything, the great mental strength to recover quickly from the mistakes which can befall them and which have consequences more dramatic than any outfield player is liable to suffer.
By the very nature of being the last line of defence, the pressures on a keeper are unique.
A particular set of skills is called for, including an inner strength.
Many insist that a keeper needs presence.
Usually that is code for being around 6ft 4in and built like Steven Segal.
That, in my book, is nonsense.
The top keepers in the last 25 years in Scotland have been Andy Goram, Stefan Klos and Jim Leighton.
Goram never touched 5ft 11in his socks, Klos just made 6ft and Leighton was never in danger of concussion from hitting his head off the underside of the bar.
All three, though, exuded capability and confidence, along with the ability to remain unflustered and in command in pressure situations.
All were confident enough in their own skins to hold their line and refuse to come for balls in a reckless fashion, which could be better dealt with by defenders.
In England Brad Friedel and Shay Given are two prime examples of top-class custodians.
Age seems to be an important factor too in improving goalkeepers.
The top men are now seeing careers which allow them to play to 40 and perhaps beyond.
It's a great joy to watch all players perform their art at the highest level.
The meandering Lionel Messi on a mesmerising run is a thing of beauty.
The thrill of a Cristiano Ronaldo free kick swirling and twisting into the top corner of the net is a moment of magic.
But matching both in its own unique and special way is the craft and artistry of the great men who guard the nets.
