The ‘unpredictable’ Thomas Tuchel ‘irritates Bayern Munich bosses with his odd behavior on transfers’ after trying to fight for Declan Rice while they eye Harry Kane

Bayern bosses are reportedly furious with Thomas Tuchel for his “erratic” behavior during the summer transfer window.

The Bundesliga giants have signed five players, including Harry Kane, in a club-record £100m deal from Tottenham this summer.

One area where Tuchel was keen to step up at the No6 position: the former Chelsea manager had an interest in Declan Rice before joining Arsenal, while the German giants were also without Fulham’s Joao Palhinha.

After the 2-1 win over Borussia Mönchengladbach, Tuchel told reporters: “The squad is a bit thin, a bit small.” “We have six trained defensive players for a back four, that’s perfect.”

As reported by PICTURETuchel’s “repeated negative remarks” have angered Bayern bosses, who feel his public demands are fading.

Internally, Tuchel’s behavior during the summer window was described as “erratic”, with many players’ names brought into play and bosses feeling he was trying to be “too creative”.

One of their disappointments was Tuchel’s push to sign Rice even though they felt Kane took precedence.

It would have been unlikely for the club to sign both players as Rice cost Arsenal even more than his England team-mate at £105m.

Bayern’s transfer committee felt that signing a number 6 was more important for Tuchel than signing a striker, but after signing Kane they accepted his demands and pushed for Palhinha after the manager made the public demands.

The German club initially made an offer of £47m but this was later rejected by the London club who initially set a price of £90m for him.

The move fell through as the London club failed to find a replacement in time – even if the German window closed earlier than the English.

This came despite the Portugal international arriving at Bayern Munich to have his picture taken with the club’s kit.

Tuchel’s comments about the thin squad were made after the transfer window had closed and are said to have caused “complete misunderstanding among the club’s management”.

The German giants had been linked with a host of other players during the transfer window.

After selling Benjamin Pavard to Inter Milan, Bayern Munich considered signing another defender.

However, it is said the club have not approved the signing of Chelsea’s Trevoh Chalobah or Germany international Armel Bella-Kotchap.

Tuchel reportedly agreed to the re-signing of Joao Cancelo, who was on loan from Man City last season, but changed his mind after consulting with his coaching staff – the Portugal international had been there since joining Manchester City.

Bayern bosses also hoped that Tuchel would be “clearer” about the profile of the goalkeeper he was looking for as they searched for a replacement for the injured Manuel Neuer.

The former Chelsea manager reportedly came up with new proposals repeatedly, including Bono, Kepa Arrizabalaga and Robert Sanchez before finally signing Israeli Daniel Peretz.

Bayern also signed Kim Min-jae from Napoli over the summer, with Konrad Leimer and Raphael Guerriero joining after their contracts at rivals RB Leipzig and Borrussia Dortmund respectively expired.

Tuchel narrowly managed to give the club the Bundesliga title last season after replacing Julian Nagelsmann in March.

This came as Borussia Dortmund drew 2-2 with Mainz, while Bayern Munich clinched a dramatic late win against Cologne on the last day of the game.

Despite the club’s frustrations with the manager, Bayern have a 100 per cent winning record at the start of the season, with three straight wins to start their Bundesliga title defense.

In the Champions League, they were drawn in a group alongside Manchester United, Galatasaray and Copenhagen.
