Jose Mourinho made a winning return to Stamford Bridge as Chelsea beat promoted Hull City 2-0 in the Premier League on Sunday after an early Frank Lampard penalty miss.
Brazil's Oscar put Chelsea ahead on 13 minutes, slotting home low past goalkeeper Allan McGregor from Kevin de Bruyne's though-ball into the box.
Lampard, who had his sixth-minute penalty and also a 15th-minute shot saved by McGregor, eventually got on the scoresheet with a free kick that dipped in under the keeper's bar for a 2-0 lead in the 25th.
The newly installed goalline technology passed its first test when McGregor saved a header from Branislav Ivanovic on his line in first-half stoppage time and replays confirmed the keeper had clawed the ball out before it had fully crossed over.
Soldado penalty gives Spurs opening win
Earlier, Spain striker Roberto Soldado's penalty on his Premier League debut gave Tottenham Hotspur a 1-0 win at Crystal Palace in their opening match of the season.
Spurs, who were not awarded a single penalty last season, were given the spot kick early in the second half for an unfortunate handball by Palace defender Dean Moxey as he tried to block a dangerous Aaron Lennon cross.
Soldado, a 26 million pound ($40.60 million) signing from Valencia, then coolly slotted his effort inside Julian Speroni's right hand post with the keeper going the other way.
"Roberto's a real out and out striker.
"He's not been here a lot because of the Confederations Cup but he'll get fitter and sharper and will be even better," Spurs manager Andre Villas-Boas told reporters.
