Southampton's Nathaniel Clyne says his side are "buzzing" for upcoming games against Manchester City, Arsenal and Manchester United.
Full-back Clyne scored in the 1-1 draw with Aston Villa on Monday as Saints remained second in the Premier League.
And the England defender says they are determined to show how good they are.
"We're buzzing for it. There are some big games coming up thick and fast and we have to be mentally prepared," Clyne, 23, told BBC Radio Solent.
"We're going into those games confident. We are underdogs but want to show how good we are."

|"Going away with the international team, getting my first and second caps, playing well - I'm happy with my progression and hopefully I can get better and be the best I can be."|
Clyne won his first two England caps this month after a fine start to the season with Southampton.
His contract will expire in the summer of 2016, but Saints boss Ronald Koeman has confirmed the club have opened talks about a new deal.
"I know Clyney's contract has one year left after this season, so it's normal to do something now to keep that player," said the Dutchman.
"Have those talks already started? Of course, you cannot wait until next season."
He continued: "We want to keep everyone and I am not surprised about Clyne's performances for the national team.
"He is a fantastic player which he has showed since the start of the season. If there is interest, we will hear about that and we will try everything to keep him here because he is a fantastic football player."

Clyne admitted to being delighted with his international introduction against Slovenia and Scotland and is determined to build on the experience.
"Going away with the international team, getting my first and second caps, playing well - I'm happy with my progression and hopefully I can get better and be the best I can be," he added.
"It makes me more confident and into a better player, I feel like a leader here so I've got to show my experience and help out the team."
