Emi Martinez is getting a wake-up call about what it really means to be a modern goalkeeper, especially after his recent mistakes against Chelsea and Arsenal.

He’s been spending extra hours with Aston Villa’s coaches, trying to get better at dealing with high balls. Corners have been a problem—Villa have let in the first goal from set pieces in their last two games.

Villa did manage to turn things around at Chelsea, but Arsenal didn’t let them off the hook. They hammered Villa 4-1 and pulled six points ahead of Unai Emery’s team. Emery’s frustrated. He thinks goalkeepers just don’t get the protection from referees that they used to. He even joked that soon, keepers might have to be over seven feet tall—and maybe wear boxing gloves—to have a chance.

Emery said, “Maybe in the future we’ll need goalkeepers who are 2.2 meters tall. Maybe we need boxing gloves, too.”

He’s watching Martinez work with the goalkeeper coach, trying to keep up with the way football keeps changing. Referees look at these situations differently now. Usually, Martinez is strong in those moments—corners, long throws, all that. But when there’s pushing and blocking, referees are letting a lot more go. Emery’s seeing it in every game, even when Villa are attacking.

“At set pieces now, players are all over the keepers—pushing, blocking—and it’s not getting called as a foul. It’s getting harder. Sometimes two or three guys are blocking the keeper at once. That’s just how it is for every keeper right now,” Emery said.

He admits Villa can use the same tactics, but they’ve got to adapt and get sharper at defending those moments.

And you can bet Sean Dyche has been paying attention to Martinez’s struggles. Dyche brings his Nottingham Forest squad to Villa Park this weekend, with Simon Hooper set to referee. This won’t be an easy one for Villa’s number one.

Brennan Johnson just sealed his £35 million move from Tottenham to Crystal Palace. The 24-year-old Wales international signed a four-and-a-half-year deal at Selhurst Park.

Johnson led Spurs in scoring last season but lost his spot under Thomas Frank. Now, he’s set for his Palace debut against Newcastle at St. James’ Park on Sunday.

“I’m really excited and happy,” Johnson said. “Crystal Palace is a club I’ve always admired. The timing feels perfect, and I can’t wait to be part of what they’re building here.”

Palace manager Oliver Glasner sounded thrilled, too. “Brennan gives us real attacking options with his speed and eye for goal. Full credit to the club for moving so fast to get this done. With so many matches coming up, he’s a huge addition for us.”

Last season, Johnson netted 18 goals and scored the winner in the Europa League final against Manchester United—finally ending Tottenham’s 17-year trophy drought. But after Frank came in and brought in Mohammed Kudus, Johnson found himself mostly warming the bench.

He wasn’t even in the squad for Tottenham’s 0-0 draw with Brentford on New Year’s Day. Less than a day later, Palace announced his signing.

For Glasner, Johnson’s arrival is a lifeline. After a 1-1 draw with Fulham, the manager admitted his thin squad was stuck in “survival mode.”

Palace have been stretched all season, juggling a heavy fixture list after their FA Cup win sent them into the Conference League. The Fulham game was already their 31st of the campaign, and Glasner only had 14 fit first-teamers to pick from.

Johnson’s signing brings some real excitement to South London. He’s Palace’s first big investment since Eberechi Eze left for Arsenal in August.

Chairman Steve Parish said, “We’re delighted to have Brennan—a young talent with a fantastic record in domestic, continental, and international football. We believe Palace is the perfect place for him to keep growing, and he gives us more firepower in what’s turning into our busiest season ever, including our first time in Europe.”

Palace, sitting 10th, heads to Newcastle on Sunday, hoping to snap a six-game winless streak.
