Tottenham take on the Swiss champions tonight and we run the rule over the five most important players who may just put a spanner in Andre Villas Boas' work
Of the seven sides they could have faced there is little doubt FC Basel of Switzerland would not have been one to strike fear into their bones.
However the Swiss side are in stunning form with just one defeat from their last 15 games and they dispatched of Liverpool’s conquerors Zenit St Petersburg in the previous round.
If you are in any doubt of the threat carried by Basel’s European experience; then just direct your questions to Manchester United fans.
But who are the five key players Tottenham should fear in this tough Europa League tie?
Linked with signing for Arsenal last summer the Austrian international is just 22-years-old but has already played over 150 games in professional football.
His performances at the heart of the Basel defence have been key to their success this season and there is little wonder why so many of Europe’s big teams have come knocking about his availability.
In the absence of Chilean international Marcelo Diaz (one of three key men suspended for the first leg) it is likely that Swiss legend Frei will be handed the responsibility of playing behind the front-man.
The 33-year-old retires from professional football on April 15th to become Sporting Director at FC Lucerne so this is his last hurrah in European football. He will be looking to go out with a bang.
The giant striker is capable of scoring goals against the best and leads a solitary front-line all on his lonesome with aplomb.
If he gets a chance be sure he will be on target.
Perhaps the most dynamic Basel player on the pitch will be Valentin Stocker; even if he is asked to fill in at left wing-back this evening.
The 23-year-old has plenty of pace and a deadly accurate delivery that could cause issue should it fall on the head of Streller.
If Tottenham do not progress have little doubt; this man will have played a huge part in it. The Swiss keeper is reportedly wanted by Lyon and Barcelona and there is a reason for this clamour.
An excellent shot-stopper, quick off his line and renowned for his distributive skill Spurs have to get past him first.
How do you think Tottenham will get on?
