Birmingham beat Wrexham to the League One title last season, but it is the Welsh club who have splashed the cash ahead of the new season with six summer signings and Wales striker Nathan Broadhead reportedly set to join the Red Dragons in a club-record ÂŁ7.5million transfer from Ipswich.
âWeâve got to (keep spending),â NFL quarterback great and Birmingham shareholder Brady told The Sports Agents podcast.

âWeâve got to keep up with one another. Wrexham have, Iâd say, done an incredible job. I mean, you canât be anything but excited about what theyâve done for that club⌠Iâm so impressed by Wrexham.
âWhat they do on the pitch, off the pitch, and again, theyâre in a great position to succeed as well.â
Asked about the rivalry in a fixture that has been dubbed the âHollywood Derbyâ, Brady said: âWeâre going to talk a lot of smack in the meantime between all of us, because itâs pretty fun theatre, and I think thereâs some little friendly side bets going on.
âBut make no mistake, the people who are going to decide the fate of those games are the players wearing those jerseys.â
Brady made 10 Super Bowl appearances and had seven victories â both individual records â in a storied 23-year NFL career between 2000 and 2022.

The 47-year-old admits he would love to bring the Super Bowl to Birmingham once the clubâs new 62,000-seater stadium is built in Bordesley Green.
He said: âThat would be pretty amazing. I donât make all those decisions. Iâm not sure how much I can influence those decisions.
âBut I think that my partner, Tom Wagner (Birmingham chairman), is an incredible man, incredible businessman.
âHe has huge ambitions for the club, and I would never bet against anything that he tries to accomplish.â
Former Celtic and Tottenham coach Chris Davies steered Birmingham to League One glory with a record 111 points from 46 games.

The previous season Birmingham were relegated to the third tier for the first time in 29 years, with former England captain Wayne Rooney having been sacked in January after just 15 matches in charge.
Brady said: âI think thatâs a very natural part of a growth process, that you are going to face adversities along the way.
âWhen I look back at those years, Iâm very proud of what we accomplished because of what we overcame.
âWhatever happened two years ago or a year ago makes really no impact on where weâre at now.
âI think this club has a great manager. The expectations and standards have been set at a different level, and weâre going into this Championship season with great excitement.
âWe want to restore it (Birmingham) to the glory that itâs been in the past. To move up and to be promoted to the Premier League is a very daunting task, but it can be achieved.â
