Patrick Mahomes is fully aware of the poor relationship he has with Buffalo Bills fans.After all, he and the Kansas City Chiefs have inflicted so much pain on them as they’ve blocked the Bills from four Super Bowls since 2020 with four playoff wins over them.Mahomes and Allen will clash once again on Sunday in what would be a preview of a potential AFC Championship gameGETTYThe most recent of that came in January when the Bills lost 32-29 in the AFC Championship game. Perhaps the most memorable was in 2022 when the Chiefs won in overtime with a 42-36 victory in their divisional matchup.Mahomes needed just 13 seconds to complete two passes for 44 yards, which allowed Harrison Butker to tie the game with a 49-yard field goal and force overtime right at the end of regulation. And as the Bills and the Chiefs – who have hit second spot in talkSPORT’s Super Bowl contenders list – get ready to face off once again, Mahomes has been candid about how he thinks the Bills fans view him and his team.“They (Bills fans) don’t like us,” Mahomes told reporters ahead of Sunday’s game. “They do not like the Chiefs.The Chiefs QB is returning to his very best form but is currently beaten out of top spot in talkSPORT’s quarterback season rankings and he does not expecting a warm welcome at Highmark Stadium.“It’s a cool environment. I love playing in historic stadiums and that stadium has had so many great players play in it. Who knows, it might be the last time that we get the opportunity to play there,” he added.“It will be a great challenge for us and they’re loud and that’s what you want, you want to go in and be in a hostile environment. “That’s what football – when you watch on TV as a kid growing up – is the environment you want to play in.“It’s just a lot of great football players that we’re going up against and we know it’s going to take our best football. Mahomes has been honest about how he thinks the Bills fans view him and his team.GETTYAfter a slow start, Mahomes and the Chiefs look back at their bestGetty“That’s the biggest thing I’ve learned from this rivalry is that it’s going to be one play here or there that’s going to change the outcome, and you have to go out there and make it.”Chiefs-Bills renew AFC rivalryWhile Sunday’s game isn’t as high-stakes, the Bills know how to beat their fellow AFC contender when it comes to the regular season.Despite the postseason woes, the franchise has won four consecutive games against the Chiefs.But the Bills know it’s the playoff games which matter, and it’s why the team, despite being on the end of so many heartbreaking losses, has respect for Kansas.$330 million quarterback Josh Allen told reporters this week that he and Chiefs defensive coordinator Steve Spagnuolo have “mutual respect.”“Sometimes it just kind of happens, we’re walking by and sometimes we look for each other,” Allen, who is 4-1 in the regular season against the Chiefs, said. The Chiefs have inflicted pain many times on the Bills in recent years, including in the 2024 AFC Championship game.Getty“Yes, I would say there is mutual respect, at least I hope there is.”Dan Orlovsky: Buffalo ‘must win” on SundayTalking on ESPN’s “Get Up” program, former NFL quarterback Dan Orlovsky claimed that it’s Buffalo who ‘need’ the win on Sunday.“This is a must-win for Buffalo, and I go back to why last season ended the way it did,” Orlovsky said.“If you go to this match-up at home in Buffalo, Josh Allen has that massive run on fourth down, that basically salts the Chiefs away.“Then you go to the playoff game, that fourth down that was on the road in Kansas City, where he’s running around against that pressure, no plan for the protection, and it’s a Hail Mary heave up, which ends up being somewhat of a drop by [Dalton] Kincaid.“For Buffalo to get to the Super Bowl, that game in the playoffs needs to be in Western New York.”Stay up to date with the latest from the NFL across all platforms – follow our dedicated talkSPORT USA Facebook page and subscribe to our talkSPORT USA YouTube channel for all the news, exclusives, interviews and more.
