Celtic are willing to compromise with Arsenal over Kieran Tierney.

The Gunners were knocked back with an initial bid of £15m for the Scotland international.

Celtic were seeking £25m for their academy graduate, but that has now changed.

According to The Guardian, the Bhoys would accept an offer of £18m for the 22-year-old.

The news means a deal is far more likely as the North London club are looking to save as much of their £45m transfer budget as possible.
