Chelsea boss Jose Mourinho says winning the Europa League would be a "big disappointment" - only a few months after rival Rafael Benitez guided the Blues to victory in the tournament.
.
Chelsea won Europe's second-tier club competition last season after failing to defend their Champions League title.
.
But Blues boss Mourinho told BBC Sport: "I don't want to win the Europa League.
.
"It would be a big disappointment for me. I don't want my players to feel the Europa League is our competition."
.
Benitez guided Chelsea to Europa League success in May by beating Benfica in the final.
.
The 53-year-old Spaniard, who took over at Stamford Bridge on a short-term basis in November, also helped the club clinch automatic qualification for the Champions League, a competition the club won in 2012 when Roberto Di Matteo was in charge.
.
Mourinho, who has clashed verbally with Benitez on a number of occasions, has never won the Champions League while at Chelsea but did taste success with Porto in 2004 and Inter Milan in 2010.
.
"That's the only European competition we have to play and that's the European competition we have to give our best," he told BBC Sport's Richard Conway.
.
As well as conquering Europe, Mourinho is also targeting Premier League success after guiding the Blues to league glory twice during his first spell at Stamford Bridge.
.
"The most important thing in football is to be the best team in the season and try to win your domestic league," said the 50-year-old Portuguese, who was Blues boss from 2004 to 2007.
.
"In our case, it's the most important league in Europe, so we have to try and be the best team and win the Premier League."
.
As Chelsea prepare to face Singha All-Stars in Bangkok on Wednesday, the former Real Madrid manager has told his squad that status does not matter when it comes to team selection.
.
Defender John Terry, 32, and Frank Lampard, 35, were key members of the team during Mourinho's first Chelsea reign, but he insists no one is guaranteed their place.
.
"I don't care about the passport, I don't care about the date of their birth, I just care about performance," he said.
.
"If they are better than the young guys, then they play. If the young guys are better than them, they don't play.
Jose Mourinho has always be known to be annoyingly arrogant so let's just see how far he'll go next season. If he flops again, let him be sacked.
