Manchester United defender Phil Jones has said that his team will need to be at their best to overcome Middlesbrough in the League Cup on Wednesday.

The Premier League outfit will enter the fourth-round clash as the favourites to book their spot in the quarter-finals.

However, Jones, who has recently returned from injury, has warned his side that Middlesbrough will be extremely motivated to claim a scalp.

"Middlesbrough are a good Championship team, they have played well this season and it will be a different game for us," Jones told MUTV.

"They're coming to Old Trafford, playing under the floodlights and it's a massive game for them. Some players have probably never played at Old Trafford, so that's the incentive they have.

"We need to make sure we turn up and do our job. Just because they're in the Championship doesn't mean we're going to win the game; we need to play well and hopefully we can win it because this is a competition we want to do well in."

Middlesbrough, who have already beaten Oldham Athletic, Burton Albion and Wolverhampton Wanderers in the League Cup this season, currently sit fourth in the Championship table.
