Arsenal defender Kieran Tierney is ready to make his Premier League debut on Monday, according to manager Unai Emery.

Tierney, 22, joined from Celtic in the summer for a fee of £25m on transfer deadline day. However, he is yet to make his mark in the league campaign due to his double hernia operation at the end of last season with the Bhoys.

Despite this, he has played a significant part in Arsenal's Europa League and Carabao Cup campaigns respectively, even getting compared to Ashley Cole by Arsenal legend Alan Smith.

Emery confirmed during his press conference that Tierney will be available for selection on Monday, simply stating: "He is ready to play."

Throw him in at the deep end

With Arsenal having spent a significant amount of money on the 22-year-old and after his contributions in the domestic and European competitions so far, Tierney must feature if fully fit and he will become a valuable part of Emery's team.

The Scotsman was credited by Liverpool's Andrew Robertson for being "different class" during an interview with BBC Sport.  The Arsenal left-back was asked to play on the right for Scotland, and proved he has the versatility and quality to help the team wherever he plays.

Last season, the Scotland international provided five assists in 20 Scottish Premiership appearances, and built up 37 assists in 170 total games for the Hoops in all competitions.

Former Arsenal striker John Hartson even likened him to Robertson, but actually believes he is a better player defensively, per the Daily Record (via the Metro).

As a five-time Scottish league champion, the former Celtic youngster has the winning mentality to boost the Gunners squad. Former Bhoys teammate Kris Commons told Football Scotland that his desire to win has never fazed him, despite previously breaking his leg during his early years.

Tierney has the potential to become one of the best young players in the Premier League. Combining his ability, versatility and attitude will give Emery a crucial asset, and one that must start from the off on Monday if he truly is "ready to play".
