Poland vs. SCOTLAND: National Stadium, Warsaw, 20:45 local/19:45 GMT/14:45 ET
The big news is that Darren Fletcher is back in the Scotland squad to play Poland on Wednesday night. Fletcher was captain of the Scots when illness struck, and though he may not start, there is both genuine excitement and actual pleasure in seeing him return. Certainly his teammate Barry Bannan is pleased: the Crystal Palace midfielder told the BBC that "Darren's like the daddy of the team." Which is adorable, obviously, but does nothing to shake the suspicion that Bannan is in fact about twelve years old.
ENGLAND vs. Denmark: Wembley, London, 20:00 GMT/15:00 ET
Meanwhile, at Wembley, five United players are part of England's squad to face Denmark. Wayne Rooney will almost certainly start, run around a lot, kick at least one Danishman for no particular reason, then be subbed after about an hour. He might score a goal in the process. Danny Welbeck will probably get a cameo in the second half, as the cycle of substitutions begins and the game sags like an abandoned balloon. The other United players hoping to get another cap are Michael Carrick, Chris Smalling, and Tom Cleverley; should the latter get on at any point, expect the internet to be exceptionally upset about it.
Australia vs. ECUADOR: The New Den, London, 20:00 GMT/15:00 ET
"Hello, Virgin Trains? Yes, hello. My name is Antonio, and I'm travelling from Manchester to London on Wednesday. I was just wondering if I could switch seats? Yes, I'd like to sit by the window. No, no, the other window. Yep, that's the one. On the right. Thank you very much. And the same for the way back, please."
FRANCE vs. The NETHERLANDS: Stade de France, Paris, 21:00 local/20:00 GMT/15:00 ET
Hot United-on-United action here, as Patrice Evra and Robin van Persie line up on opposite sides. Evra may not start, but Van Persie should, and this presents United fans with the opportunity to a bit of detective work. Should Van Persie skip onto the pitch with a beaming smile, score seven, then cartwheel off giggling as flowers bloom around his feet, then we can safely assume his recent United funk is entirely the fault of David Moyes and prepare pitchforks accordingly. Alternatively, should he look his usual miserable self, then we can just file him under 'mardy sod' and move on with our lives.
JAPAN vs. New Zealand: National Olympic Stadium, Tokyo, 19:30 local/10:30 GMT/05:30 ET
Speaking of a player who might feel liberated from whatever's going on at the club, Shinji Kagawa has the chance to put all the unpleasantness -- all the arguments about whether's he being used wrong, or being ignored, or just being rubbish -- behind him for a few days. At last year's Confederations Cup, Japan played some superb football and caused everybody problems; expect them to hammer New Zealand, expect Kagawa to play well, and expect the arguments to kick off again with renewed vigour as a result.
MEXICO vs. Nigeria: Georgia Dome, Atlanta, 20:30 local/01:30 GMT (that's Thursday morning)
Speaking again of a player who might feel liberated from whatever's going on at the club, Javier Hernandez is off to unburden himself with a Mexico side that were, for much of qualification, a complete and total shambles. Oh, Javier! That's not going to help! Still, new coach Miguel Herrera saw them through the playoffs, likes his teams to attack, and is looking for a spearhead after Giovani dos Santos picked up a knock of as-yet-unclear seriousness. There's always one player who follows up a disappointing league season with a belting World Cup, and it would be great fun if it were Hernandez.
BELGIUM vs. Ivory Coast: King Badouin Stadium, Brussels, 20:45 local/19:45 GMT/14:45 ET
Speaking again -- well, you get the idea. Indeed, perhaps the only player at Old Trafford more in need of a break than the two above is Fellaini, who has looked largely overawed in his time at the club so far. Go and chill, Marouane. Have a waffle. Have two waffles. Clank around in midfield for a bit, like the old days. Smile.
GERMANY vs.Chile: Mercedes-Benz Arena, Stuttgart, 20:45 local/19:45 GMT/14:45 ET
Well, Toni Kroos might play, and it's important that when he signs his new contract with Bayern Munich, everybody's in a position to say "Obviously he's great with Bayern, but when I saw him with the national team I had my doubts about whether he'd fit United's style of play". It doesn't have to be true, of course. Besides, Germany and Chile are fun to watch.
England U21s vs. Wales: Pride Park, Derby, 18:00 GMT/13:00 ET; England U19s vs. Turkey: Chester, 19:00 GMT/14:00 ET
Finally, the young uns. Will Keane, Jesse Lingard, Wilfried Zaha and Sam Johnstone are taking on Wales with Gareth Southgate's U21 side (as is former Manchester United prospect Ravel Morrison, should you be interested). Meanwhile James Wilson has earned himself a call-up to the U19s. The best of luck to them all.
