Squad

A fracture rules Philipp Mwene out for 23 days

Bones knit. That is the one merciful thing about this injury and the reason Mainz 05 will talk about it more openly than they would about a knee. He will be back, and roughly when they say.

Market

Mainz 05 spend $20.3M to raise the standard

This is not cover and nobody is pretending it is. $20.3M has been paid because Tim Lemperle is straightforwardly better than what was already here, and the club has decided to stop waiting.

Transfer targets

Mainz 05 agree $6.3M for Ayo Akinola

The clubs have shaken hands with Vaduz; the player has not yet. Personal terms are next, and personal terms are where more deals die than anybody prints.

Transfer targets

Door shut on Nicolò Tresoldi

Mainz 05 asked and Club Brugge said no without discussing a figure. It is the least ambiguous answer in football and the one clubs most often come back to test.

Squad

Alynho Haïdara in a row with a teammate

It was not about football and everybody who saw it knows that. Two men who have to play together on Saturday said things at Mainz 05 this week that will take longer than a week to unsay.

Squad

Kaishu Sano falls out with a teammate over standards

The oldest argument in any dressing room and the only one that is genuinely about football: one man thinks another is not putting enough in. It is also the row a manager privately does not mind having happened.

The terraces

The town asked, and Mainz 05 paid $20.3M

Tim Lemperle was the name on every phone-in, and the club has gone and signed him for $20.3M. For one week the board can do no wrong, which is a week most boards never get.

Squad

The formation has left Tim Lemperle behind

Every shape has positions in it and this one does not have his. Mainz 05 will either change the shape, change his job, or change his club, and he is waiting to hear which.

Boardroom

Mainz 05 say no to the training-ground money

The plan went upstairs and came back down. Nothing about that will make a headline anywhere else, and everybody who works at the training ground will remember it for years.

In brief

Transfer targets

An offer of $23.1M for Nathan Tella

Mainz 05 have gone to Bayer Leverkusen with a bid, and the supporters have gone to the internet with an opinion about it. Whether either changes anything is up to the selling club.

Transfer targets

Mainz 05 rebuffed over Fisnik Asllani

Not now, not at any price the club was prepared to say out loud. TSG Hoffenheim have kept their man, and Mainz 05 go back to a list with one name crossed off it.

Market

TSG Hoffenheim come back empty-handed

The bid was some way short and Mainz 05 did not need long over it. Nobody in the game reads a first refusal as the end of anything.

Squad

Nadiem Amiri stays put

“The easiest signature of my career.” Nadiem Amiri and Mainz 05 agree another 5 years, and the manager can plan around him rather than about him.

Transfer targets

Nikolai Rehnen due for a Mainz 05 medical

Everything agreed with another club, everything agreed with the player; a doctor is the only person left to persuade. The photograph is a day or two away.

Squad

Words exchanged at Mainz 05

Nadiem Amiri and a teammate said things this week that will take longer than a week to unsay. It was not about football, and both of them play on Saturday.

Squad

A row about effort at Mainz 05

Somebody said out loud what several people thought about how hard another man trains, and Alynho Haïdara was in the middle of it. The one dressing-room argument that is genuinely about football.

The dugout

Phillip Tietz gets it from the manager

“Nobody here is above being told.” It was not said with a name attached, but the dressing room can count, and so can everybody who was listening.

Market

One of our own: Robert Hartmann joins the Mainz 05 first team

Clubs spend fortunes looking for players and occasionally find one down the corridor. Robert Hartmann is that, and the reception he gets on his first appearance will be different in kind from the one any signing receives.

In brief
