Frank Lampard has claimed that Chelsea are in a "good position" following Thursday's 1-0 win at Sparta Prague in the Europa League.
Oscar scored the only goal of the game in the first leg at the Stadion Letna to give the Blues the upper hand in the last-32 tie.
"We still have to concentrate to make sure we get the right result but we're in a good position now so we have to follow it though," Lampard told UEFA's official website.
"The Europa League is a fantastic competition to try and win, so that's what we have to do."
Chelsea welcome Sparta Prague to Stamford Bridge for the second leg next Thursday.
