Chelsea will play Derby City in the FA Cup 3^rdround on Sunday in a game that encapsulates what the FA Cup is about. Derby fans will be excited to welcome Jose Mourinho and his team of millionaires to the iPro Stadium, and will be hoping to cause a massive upset.

Today's big game will kick off at 2.15 p.m. GMT and can be watched online through live stream – free for Fox Soccer 2 Go subscribers – via the link provided below.

For Chelsea defender David Luiz could return after suspension. However, injured trio Frank Lampard (muscular injury), Branislav Ivanovic (knee) and Marco van Ginkel (knee) all remain unavailable.

Chelsea manager Jose Mourinho has said ahead of the game: "Do we lose? Do we win? Who knows? At least the message is we respect them and we go there with the best possible team."

He added, "The next game after Derby is Hull at the weekend. We can play against Derby and have a day off on Monday. I think the players are also keen on it, to go with a strong side and at least tell our opponent that we are going there with maximum respect."

Meanwhile former England manager, now Derby manager, Steve McClaren, has said, "This is a huge test for us and we're up against a side that, I would expect, will finish in the top two in the Premier League. I'd be surprised if they don't. The players need to show self-belief and that comes from demonstrated ability, as confidence does, and we would like to think we have built it up over the last few months."

He added, "It's about us too - we know how good Chelsea are but we need to remember what we do well every week and not go into our shells."
