Celtic fans have taken to Twitter to react after the club tweeted out a letter written by Neil Lennon.

The message is an emotional one, in which the former Bolton manager expresses his love for the club and how he has always had Celtic in his heart as a player, captain and now as boss of the Hoops.

It is primarily a plea for supporters to renew their season tickets for next term, rather than Lennon wearing his heart on his sleeve just for the sake of it, which adds a cunning nature to the post - something that some supporters below have picked up on.

Peter Lawwell has picked a very good time to convince the Celtic Park faithful.

The Bhoys are into the semi-finals of the Scottish Cup and are also 13 points clear of Rangers at the top of the Scottish Premiership, so times are good at the club which will obviously help persuade fans to dig into their pockets and sign up for next season.

However, because of that, and the fact that Lawwell hasn't invested much money into the playing staff recently - the Hoops supremo spent over £17m back in the summer, but had sold Kieran Tierney for £25m - a few fans below aren't happy with this PR stunt.

Let's see what they've been saying on Twitter...

To kick off the reaction, these three supporters were all saying what we had previously mentioned above.

They accuse Lawwell of tugging on the heartstrings of emotionally-invested supporters, while not investing in the squad.

While - as aforesaid - over £17m was spent in the summer, Lawwell has overseen the departures of Virgil van Dijk, Moussa Dembele and Stuart Armstrong in recent years, while Odsonne Edouard has arguably been the only signing to have significantly made a groundbreaking impact.

Elsewhere, another told the club to calm down with the "nonsense" as it's only March.

Two other fans mocked the way in which the letter is portrayed - the club did a video of a magnifying glass-type effect enlarging the message, scrolling down the page very, very slowly while playing dramatic music in the background, for some reason.

The Celtic marketing team has been working into overdrive amid the calls for season ticket renewals, and while they were busy making the graphics look nice with a striped-effect across some tweets, a bunch of fans took that as a subtle hint towards Adidas' potentially imminent arrival.
