The Argentine watched his side win 2-1 in the first leg of their last-32 Copa del Rey tie but says they still have work to do in the return game
Atletico Madrid coach Diego Simeone says his side is not yet comfortable despite a 2-1 win at Reus Deportiu in the first leg of their last-32 Copa del Rey tie.
Simeone's men fell behind to the Segunda B leaders before goals from Luciano Vietto and Saul Niguez sealed victory.
The Argentinean spoke highly of the third-tier side and said his team still had work to do if they were to progress.
