According to The Sun, Tottenham have stepped up their pursuit of Celtic defender Kieran Tierney, who has been impressing scouts around Europe for the last 12 months.

What's the Story?

Mauricio Pochettino sent scouts to Munich last Wednesday to watch Bayern's comfortable Champions League victory over Celtic. However, the Spurs representatives were not eyeing Robert Lewandowski or Arturo Vidal.

Instead, Celtic's young defender Kieran Tierney was the reason behind the trip to Germany, with Tottenham reportedly interested in landing the 20-year-old at some point over the next two transfer windows.

This is not the first time that Spurs representatives have been seen watching the left-back. Scouts were also present when Celtic edged past Kazakhstan outfit Astana during the Champions League qualifying stages.

How good has Tierney been this season?

Expectations rose for Kieran Tierney when he was awarded the Scottish Premiership Young Player of the Season award in 2016/17. It wouldn't have been a surprise to see the young defenders form drop somewhat this season because of this pressure.

However, the opposite has seemingly occurred and Tierney has actually improved markedly since last season. The 20-year-old, who is valued at £1.8million by Transfermarkt, has featured in 14 games for Celtic so far this campaign and has been one of the most consistent performances in Brendan Rodgers' side.

Would Tierney be a good signing for Spurs?

One of the brightest talents in Europe, Tierney would certainly be an astute signing for Spurs, especially if he continues to develop his game.

The likelihood of this signing coming to fruition depends on Danny Rose and whether his recent feuds with Tottenham can be forgotten. If not, and the England international is moved on, Tierney would be a superb replacement.
