Just a few days before the August 31 deadline, Arsenal finally gave their fans something to cheer with the big-money arrivals of Shkodran Mustafi and Lucas Perez for a combined £52 million.
Despite their relief at Arsene Wenger finally dipping into the funds for a striker, there were, and still are, some supporters who are wary of Perez's arrival considering his relative anonymity in England. A feeling summed up by celebrity Gooner, Piers Morgan.
However, speaking today, his fellow new arrival has eased any concerns by explaining exactly what makes the Spaniard such an accomplished striker.

Mustafi has first-hand experience of coming up against Perez after the pair met twice in La Liga last season whilst playing for Valencia and Deportivo, respectively.
"He is uncomfortable to play against,” Mustafi told Arsenal Player. “He’s a good striker - he has everything a striker needs.
“He’s someone you can play well with. He doesn’t just run around and wait for someone to give him a pass to score a goal. He works a lot for the team as well and he creates chances.
“He’s in the right place at the right time, as he showed last year in La Liga.
"I played there for two years and I know it’s not that easy to score many goals in La Liga, because you have great defenders there as well."
Mustafi's description of what Perez can offer will certainly leave Arsenal fans excited to see what the 27-year-old can produce in the Premier League.
His work ethic and ability to create chances will, in a lot of fans' eyes, already have him above Oliver Giroud in the pecking order at the Emirates.
The German centre-back, meanwhile, might not be looking forward facing his fellow new arrival in training considering what happened when the pair met in Spain last season.
As we reported a few weeks back, Mustafi was left furious after Perez produced a fine finish - one of his 17 in La Liga in 2015-16 - against Valencia back at the start of the year.
Arsene Wenger will be hoping that both players can hit the ground running for their new club in the next few weeks.
Having taken four points from their opening three games, the Gunners are already five points off the pace in the Premier League.
The arrival of a potentially potent goal-scorer and experienced defender could be just what the team needs if they are to make up the ground.
