Middlesbrough has had a sensational FA Cup run full of giant killings and they will look to end the hopes of another Premier League club.
They have eliminated Manchester United and Tottenham to reach this stage of the competition and they will feel confident they can go even further.
Their home has become a fortress and they head into this match having not lost any of their last nine matches at home.
That stat shows the odds are stacked against Chelsea even though Thomas Tuchel’s side is the best in the world right now.
The Blues have won the Champions League and Club World Cup in the space of one year and they have just lost the League Cup final against Liverpool.
They have the players to win this game, but Boro has proved too strong to handle to several teams in the competition already and will now look to end Chelsea’s run.
The last time these clubs met was in 2017, but Chelsea has a solid head to head record against them, winning all their last five games against each other.
