LIFELONG Arsenal supporter Piers Morgan cannot wait to see Kieran Tierney in an Arsenal shirt and reckons he'll be a huge hit at the Gunners - because some Celtic fans have reacted angrily to the news that the defender could be sold.

And Morgan - who is famously outspoken on Twitter - is convinced that Arsenal have got the right man after seeing the 'blind fury' from Celtic fans.

He tweeted: "The blind fury I'm witnessing from Celtic fans suggests @kierantierney1 is not only a) coming to Arsenal but b) a brilliant young player."

Morgan then followed that up with another tweet, writing: "BREAKING: Arsenal appear to be having a big-spending, aggressive, surprising & highly successful transfer window. And it's blowing my mind."
