Arsenal's hopes of signing Celtic left-back Kieran Tierney have been boosted by reports the Scottish giants are closing in on landing a replacement.

According to The Sun, Celtic are closing in on the signing of Brentford full-back Rico Henry in a £7million deal.

And the impending arrival of Rico would pave the way for Tierney to move to Arsenal.

The £25m-rated Tierney is open to joining Unai Emery's side but Celtic want a large proportion of the transfer fee paid up front.

Tierney had an operation at the end of last season to deal with a double hernia.

He didn't play in Celtic's 7-0 victory over St Johnstone to start the 2019-20 Scottish Premier League season on Saturday.
