FC Basel 1893's attempt to emulate last season's run to the knockout phase started positively as Alexander Frei scored both goals in a 2-0 first-leg win against UEFA Champions League second qualifying round opponents FC Flora Tallinn.
Frei struck on 64 and 87 minutes at the Lilleküla Stadium, venue for Sunday's UEFA European Under-19 Championship final between Spain and Greece. Basel will try for more goals when the return takes place at St. Jakob-Park next Tuesday.
Things might have been different had Karl Mööl not directed over the bar a cross from the left by one of Estonia's U19 players, Karl-Eerik Luigend. Frei had a close-range shot saved by Stanislav Pedõk midway through the first half before he applied the finishing touch to a right-wing David Degen delivery after 64 minutes.
The former Swiss international doubled his and Basel's tally three minutes from time, converting from the spot after Karl Palatu had fouled Valentin Stocker.
