Transfer deadline day was very active in London, with both Arsenal and Chelsea letting go and signing new players.

Arsenal confirmed the signing of Pierre-Emerick Aubameyang from Borussia Dortmund in a £55 million deal.

Aubameyang, who left under not-so-savory circumstances, apologized to Dortmund fans after the move.

“First of all I want to say sorry for what happened during the last month,” a post on his Instagram reads.

“But I wanted to leave already last summer. Back then it did not work out, so it had to be now. Maybe it was not the best decision, but everybody knows Auba is crazy – and yes – I am a very crazy guy, hahaha.

“I made mistakes, but never had bad things in mind. I will never forget those four and a half years at Borussia Dortmund.

“You gave me the strength to be at that level I reached now. Thanks to the whole BVB family, the fans, the club, the staff and of course my teammates. Your Auba17”

To make up for losing their superstar forward, Dortmund secured the services of Chelsea’s Michy Batshuayi on loan.

The Belgian forward will be with the team till the end of the season, and Dortmund don’t have the option to buy.

Batshuayi told the club’s official website he is eager for more first-team action and has ambitions of making Belgium’s World Cup squad in the summer.

“In order to achieve my big objective, I want to play as much as possible and score many goals,” he said. “The World Cup is taking place in the summer.”

With Chelsea now a striker short, Chelsea looked to Arsenal, where it all began.  The Blues signed their rivals towering striker, Oliver Giroud, for 18 million pounds.

Speaking to Chelsea’s official website, Giroud said“Chelsea is one of the biggest teams in the Premier League. They have won maybe the most trophies in the last six or seven years. It’s a massive club and I am proud to sign for Chelsea, and I’m looking forward to playing.”
