Bayern have attempted to use the January transfer window to find cover, with key defensive duo Noussair Mazraoui and Kim Min-Jae at the Africa Cup of Nations and Asian Cup respectively.
Tottenham centre-back Dier made a surprise switch to join up with former teammate Harry Kane, while reports have suggested the Bavarian Giants are interested in experienced Newcastle full-back Kieran Trippier.
However, both moves have caught the ire of Matthaus, who criticised the slapdash nature of the decision to go after Trippier.
‘That’s not Bayern Munich for me. Bayern should focus on reinforcement or on young players,’ the former midfielder said, speaking on the Sky90 podcast.
‘Bayern Munich have very good youth players and Christoph Freund [Bayern’s sporting director] is responsible for that. He has a good network.
‘In the summer it was said, “We can let [Benjamin] Pavard and [Josip] Stanisic go and get someone else instead”, and then they didn’t get anyone else.
‘As a result, they’ve got problems at right-back and in the centre. They thought, ‘We’ll manage that’. No, they reacted too late. The team can’t find itself.
‘The difference to Leverkusen: Xabi Alonso had his team together from the start in the summer and was able to train what he wanted for six weeks.’
When asked about Dier’s arrival, Matthaus was equally scathing. ‘Bayern need more depth and reinforcements, but are these players reinforcements? Eric Dier wasn’t necessarily a key player at Tottenham recently,’ he said.
‘I remember Uli Hoeness [Bayern’s former president] once saying that, “We won’t be bringing in any more players who are sitting on the bench at other clubs.” The latest transfer looks different.’
On the pitch, Thomas Tuchel’s side lost further ground on league leaders Bayer Leverkusen at the weekend after they suffered their first home defeat of the season in a 1-0 loss to Werder Bremen.
In the wake of the defeat, Tuchel has taken aim at his players for their performance levels and attitude in training.
