The Capital One Cup Quarter-Finals commence on Tuesday, with Middlesbrough hosting Everton in the first of the week's live Sky Sports fixtures.Boro booked their place in the last eight courtesy of a penalty shoot-out win over Manchester United at Old Trafford, and were rewarded with more Premier League opposition and, most importantly, a home tie at the Riverside Stadium.
Everton also arrived at the Quarter-Final stage by virtue of spot-kicks, after they knocked out Norwich City following a 1-1 draw across 120 minutes.
We meet again
Middlesbrough and Everton have locked horns 129 times since their maiden meeting in 1902, but haven't done so for more than six years.
Their last clash came in the 2008/09 Premier League season, where the Toffees did the double over Boro in a campaign that saw the latter suffer relegation.
The last time the pair faced off in the League Cup was a decade ago, in 2005, and it was Boro on that occasion who got the better of David Moyes' Everton, with Jimmy-Floyd Hasselbaink scoring the only goal of the game in a 1-0 triumph.

One of their most memorable meetings in this competition came back in 2003/04, but not because of the game itself. Middlesbrough knocked out Everton in Round 4 – 5-4 on penalties – and it was a result that catapulted them all the way to the Final, where they beat Bolton Wanderers 2-1 in Cardiff to lift the trophy.
The here and now
Middlesbrough, after falling in the Sky Bet Championship Play-Off Final last term, are going well again, and currently sit second in the standings, just two points behind unbeaten leaders Brighton & Hove Albion.
They're in good form, with five wins from their last six games, and they've conceded just one goal during that period.
Everton, meanwhile, have been solid of late, and have alternated between wins and draws in their last four matches.
The Merseyside club are full of goals, having hit 14 in those previous four outings. Romelu Lukaku is their top scorer with 12 goals so far in all competitions, and the Belgian international joined an elite group of players to have scored 50 Premier League goals recently - the fourth-youngest player to do so.
Battle of the Spaniards
In the dugouts, two Spaniards will go toe-to-toe - Aitor Karanka and Roberto Martinez.
Karanka has recently passed his two-year anniversary at the helm of Boro, leading them to a 12th-place finish in his first year after taking charge in November, and he subsequently made the aforementioned Sky Bet Championship Play-Off Final last season.
Martinez has also been with Everton for just over two years, and guided them to fifth place in his maiden campaign. Last term, things didn't go quite so well, as the Toffees ended the season in 11th.
