Relief was the overwhelming emotion amongst Arsenal fans when Shkodran Mustafi's £35 million move was confirmed by the club.
For too long have the Gunners settled for mediocrity alongside Laurent Koscielny at centre-back, with Per Mertesacker, Gabriel Paulista and Thomas Vermaelen all failing to prove a worthy partner for the Frenchman.
But with Mustafi now at their disposal, Arsenal have a solid defensive partnership capable of bolstering their chances of Premier League glory.

So, what exactly convinced the Germany international of swapping sunny Spain for north London?
The prospect of playing for a club of Arsenal's size undoubtedly played an important role but, according to the 24-year-old, it was Germany teammate Mesut Ozil who convinced him of joining at Euro 2016.
He told the club's official website: "We were at the European Championship and we had time to speak.
"He told me about the club, about the team, and the things that he told me made me come here. I noticed that it’s a club where I can develop, where I can grow as a player.
"He said that he's happy here, that the people are crazy for football and that it's a team that enjoys playing football the way that he does, the way that I do."
As if Arsenal fans needed another reason to love Ozil.
They'll only hope that Mustafi's presence at the Emirates Stadium will persuade the 27-year-old playmaker of extending his own stay.
"I have a contract until 2018," Ozil told German outlet Express, per Sky Sports. "We have had discussions, but they were suspended for the European Championship.
"I wanted to focus at this time only on the national team. Now we look to continue the negotiations.
"In football, you can never say never. You don't know what will happen. I had a good time in Germany. That was a lot of fun.
"Eventually [moving to MLS] could be an option. I have fun everywhere. My fans know that I like to spend my vacation in Los Angeles, because the city inspires me."
Handing Ozil the vacant No.10 shirt left by Jack Wilshere might also help convince him of staying beyond his current five-year deal.
"It just went free, and I definitely want it," he said when asked about swapping shirt numbers.
Arsene Wenger risks annoying Wilshere should he give away his jersey, but if it means tying Ozil down to a new contract, so be it.
