The pundit is a regular tweeter and is never shy showing his love for Celtic.
But he wasn’t focused on the Hoops game against Borussia Monchengladbach tonight as Manchester City travelled to Barcelona in the other game of this Champions League group.
City were handed a 4-0 beating by Barcelona, with Messi putting in a sensational performance to score a hat-trick.
Collymore used the loss to further emphasise his belief that Guardiola isn’t a genius, but got this response from a follower:

And Celtic fans will love his joking response:
Didn't realise Pep had worked with Moussa Dembele? HH ☘️ https://t.co/TayO9I4fdI

Collymore has obviously been impressed with French youngster Dembele and the start he’s made to life at Parkhead.
But it’s probably not the best night to make joking comparisons to Messi after Dembele struggled to make an impact on Celtic’s 2-0 defeat to Borussia Monchengladbach.
Tonight’s results mean Barcelona lead group C with nine points, City five points off, Gladbach third with three points and Celtic bottom with one.
