For much of the summer transfer window, Arsenal fans were urging Arsene Wenger to splash more cash.
The French boss moved quickly to sign Granit Xhaka in a £30 million deal but it was starting to look as though the Swiss international was going to be the only high-profile signing the club made.
In fact, with just days remaining of the window, Wenger had only added Rob Holding from Bolton and Japan striker Takuma Asano to the Xhaka signing with Gooners getting increasingly frustrated.
However, Wenger soon signed £52 million worth of talent after completing deals for Shkodran Mustafi (£35m) and Lucas Perez (£17m).
While many supporters would have been delighted that their manager was spending money, there was one former player that was ‘surprised’ by the amount spent on Mustafi.
That man is Jens Lehmann, who believes his ex-club spent too much on his compatriot. However, the goalkeeper claims that it was Wenger’s decision to spend that amount on a defender that surprised him, rather than doubting the ability of Mustafi.
Lehmann on Mustafi
"It’s unlike Arsenal to sign a defender for almost €40m - I’m surprised," he said, per Goal.
"I think he’s probably the most successful manager in making money for the club.
"He’s always taken part in the Champions League, buying cheap and selling expensive.
"He was a major player in setting up the new stadium and at the same time always playing Champions League football."
While Lehmann may be surprised at Wenger spending big for a defender, Arsenal fans certainly won’t be.
With Per Mertesacker ruled out until the new year and Gabriel also sidelined, it was imperative that the club purchased another centre-back this summer - highlighted by the fact that Holding and Calum Chambers were in central defence for their Premier League opener against Liverpool.
With time running out, Wenger had very little choice but to pay big for Mustafi and Gooners will be very happy that he did just that.
