Explained: Why Mathys Tel's transfer to Man Utd has collapsed as Arsenal move into pole position to sign Bayern Munich starlet

The 19-year-old reportedly agreed to join the Red Devils in the final days of the transfer window, allowing United to enter negotiations with the Bundesliga giants.

Talks between United and Bayern have broken down, however, as RMC Sport reports the German giants' excessive demands have resulted in the Premier League side walking away from the deal.

While the road to Old Trafford has been blocked for Tel, he could still leave the Bavarian side before the coming deadline, with Arsenal said to be interested in him.

After losing 2-0 at home to Crystal Palace on Sunday, and reportedly giving the green light for Marcus Rashford to join Aston Villa on loan, coach Ruben Amorim will hope the Red Devils can still bring in some more firepower on deadline day after walking away from Tel.
