Ex-Manchester Utd and Everton boss David Moyes believes Celtic star Kieran Tierney would be a legend at Arsenal should he make the move down south.

Tierney, 22, has been the subject of two bids from the Gunners this summer.

Both have been booted out by the Hoops but Arsenal manager Unai Emery is expected to make another move for the left-back before the transfer window slams shut in England.

Now, speaking to the Sunday Post, David Moyes has hailed "top player" KT and insists that the defender - with a bit of fine-tuning - could become an Arsenal mainstay for the next decade.

He said: "He has been outstanding for Celtic for more than three years. 

"I've always had my eye on him and rated him. He is a top player.

"If he does go to the Emirates, I can see him being a stalwart for Arsenal for the next 10 years.

"Again, it may take him a little period of time for him to fully adjust to life in the EPL.

"He will be facing a top-end player every week, and he will need to get to grips with that as there will be much more defensive duties to carry out than he has probably been used to at Celtic.

"But if the move goes through, he will go on to show his worth and will be a credit to himself and his country."
