[ad_pod ]Tottenham Hotspur welcome Ajax to the Tottenham Hotspur Stadium this evening for a clash which nobody envisaged when the Champions League got underway.Both sides are carrying something of an underdog label ahead of the semi-final, but the calibre of the opposition they have collectively overcome to reach this stage suggests either side could lift the most coveted of footballing trophies in Madrid next month.Spurs have plenty of injury concerns ahead of the game and, with Son Heung-min also suspended, there is plenty of reason for fans to be feeling apprehensive.Ahead of the game, a true legend of the north London club, Ossie Ardiles, has taken to Twitter to publicly back Mauricio Pochettino.

This is the Argentine's biggest test of his career so far.

Pochettino will know better than anyone that this could be Tottenham's best chance to reach the final of the Champions League for years to come, even if the Eredivisie league leaders have already toppled two giants on their way to this stage.

But Ardiles' tweet underlines the feeling around the club: they are in the best possible hands and the 47-year-old possesses the nous to ensure Spurs set up a final date with Liverpool or Barcelona.

Ardiles was always the man for the big occasion during his time with the Lilywhites, as Man City know all too well, and he will be hoping his compatriot can also triumph on the big stage tonight.
