Arsenal have been warned that new signing Ben White has already set a dangerous precedent after his debut on Friday night.
The £50m man started his first Premier League match for the Gunners against Brentford, who had just been promoted to the top-tier for the first time in over 70 years.
But despite the mammoth financial differences between the two sides, the Bees claimed a 2-0 win over their more illustrious opponents.
And it could have been more as Thomas Frank's men outperformed Arsenal in almost every department.
It puts massive pressure on Mikel Arteta, whose side take on Chelsea and Manchester City next in the Premier League.
One problem that might have alarmed the Gunners coach is how easily White was beaten in the air.
The former Brighton star has many admirable traits but Ivan Toney bullied the centre-back aerially and Jamie Carragher reckons this could be a huge problem for Arsenal ahead of the rest of the season.
He told Sky Sports: "Your two centre-backs in a back four have got to be good in the air.
"When I said in commentary about being clever with your movement, when the ball comes in you ease them out of the way, using your experience.
"He is a young player but he is not going to get any taller.
"People are going to watch tonight and think just play long balls on Ben White's head and you'll get joy.
"So he either has to get someone in front of him or be a lot stronger and cleverer."
White has been linked with a number of top clubs over the past season or two after a brilliant rise to fame with Leeds United on loan and Brighton.
City, Chelsea, Manchester United, Everton and Liverpool had all been linked with the England international but had been put off by his £50m price-tag.
Arsenal were the ones in the end to shell out for the defender while Carragher has breathed a sigh of relief after admitting he did not want White at Anfield.
He added: "Ben White is not going to get too much chances to step forward with the ball and show the qualities that we all associate with him.
"You want to see him do well, there is a big price tag, and he was linked with Liverpool for the past 12-18 months.
"My fear was I would not want him to come to Liverpool because he is not tall enough and not good enough in the air.
"When you play in a back three at Brighton, you are next to two giants in Andy Webster and Lewis Dunk.
"So you can step forward with the ball and you are not too much of a problem at set-pieces and long balls."
