We landed last night. I’ve not tried a 5km run yet but I have to say that – just like Thomas Tuchel – I do have a light headache, presumably because of the altitude.Hopefully the England players are feeling better than me. The big question is who Thomas Tuchel starts at right-back against Mexico. Reece James didn’t train yesterday and is likely to be on for a place on the bench at most after missing the last two games with a hamstring problem. However there are also doubts over whether Djed Spence starts. He has a minor muscular issue and might not be risked, which means Tuchel could have to start Jarell Quansah, assuming he’s ready to go after returning from a twisted ankle.The alternatives are Declan Rice but means taking him out of midfield, which feels a bad idea, or moving Ezri Konsa to right-back and bringing in John Stones.It’s USA v Belgium on Monday (or 1am BST on Tuesday for those in the UK) and Jeff Rueter has this piece on potential tactical tweaks for USMNT head coach Mauricio Pochettino.We also have news on Belgium, who say they will need ‘balls’ to nullify home crowd in Seattle.“I’m surprised no-one is talking about hypoxia chambers, like their cousins hyperbaric chambers, are very common with elite athletes,” emails Aran Scutcher. “As I understand it they can be tents that you sleep in, or exercise in. Given the improvements are useful for endurance also at ground level, one would imagine the England players have being using these for the whole tournament.”Time now to hand the blog to Michael Butler. Thanks for reading!Hello everyone! England fans, what’s your sleep plan tonight? I am desperate to watch Norway v Brazil but might try and have a tactical nap before midnight (BST). An option for those in the UK not staying up to watch Mexico v England: BBC2 are offering a full re-run at 07:10 with no spoilers.Mexico fans try to disturb England's sleepIt’s approaching 9am in Mexico City. So, did England manage to get any sleep last night? A couple of reports below. Yes, there was noise but overall we can file this under nothing out of the ordinary.From the AP wire:Despite police blockades, dozens of Mexican fans gathered outside the England national team’s hotel until the early hours of Sunday morning, hoping to disrupt players’ sleep ahead of their World Cup round-of-16 match against co-host Mexico.Armed with loudspeakers, horns and fireworks, the crowd gathered outside the JW Marriott hotel in Santa Fe, in the western part of Mexico City and did its best to disturb the guests.Earlier in the week, “El Tri” supporters deployed the same tactics before a crucial match against Ecuador — Mexico won 2–0 — prompting the Ecuadorian football federation to file a formal complaint with organizers.England manager Thomas Tuchel anticipated the disruption but downplayed its potential impact. “We have a 6pm (Sunday) kickoff, so if we miss some hours of sleep, we’ll make them up in the late morning,” Tuchel said on Saturday.These late-night hotel “serenades” are an entrenched and polarizing tradition in Latin American football. While they began as a passionate display of support for the home team, they have increasingly evolved into a psychological weapon designed to deprive opponents of sleep.The Daily Mail also had extra detail.“Chanting ‘Mexico, Mexico, Mexico’ the supporters numbering around 50 were kept at bay by a heavy police presence which had thrown ring of steel around the complex.“Armed with riot shields and helmets, the security forces easily outnumbered the fans with around 300 officers involved in the operation.“Although noisy, they were kept a good 500 metres back from the hotel making it hard for them to disturb the sleep of England players sleep and they had been given earplugs as well as a precaution.”Videos show a band playing and fireworks repeatedly going off.Outside England’s hotel.
