With the winter transfer window now closed, we round up all of Arsenal's done deals.
The 31-year-old Italy midfielder has signed an 18-month contract, with an option to extend for a further year.
Jorginho was into the final six months of his Chelsea contract, with the Blues trying to land a British record transfer for Benfica central midfielder Enzo Fernandez.
Sky Sports News' Gail Davis:
"Mikel Arteta has made it clear in the last few weeks of the transfer window, he wants to strengthen that midfield. We know how good Thomas Partey and Granit Xhaka have been over these past few months, helping guide Arsenal to the top of the table.
"People may be surprised, when you look at the profile of players Arsenal had been signing but Mikel Arteta had made the point on the day they signed Leandro Trossard that they need players who are fit and ready to go straight off in the Premier League. That's what Jorginho is.
"Arsenal are short in the midfield area. Mohamed Elneny is out and there was no commitment from Arteta when he might be back. We know Thomas Partey picked up that injury in the cup and he's gone for an MRI on his ribs. So the squad is looking thin there.
"Europe is about to start and they'll be going Thursday-Sunday-Thursday-Sunday and they want somebody else in.
"When you look at where Arsenal are now, they've got a great chance of winning the Premier League for the first time in 20 years. Arteta understands the demands on his squad are going to be greater over the next few months and that's why he had to get bodies in today.
"Moises Caicedo is the man who's been attracting a lot of attention from Chelsea and Arsenal, who have made two bids. Brighton are saying he's not for sale.
"Had Arsenal not been in this position in the league, chasing their first title in almost two decades, would Arsenal and Arteta move in this way? But it makes it an interesting Deadline Day."
The Gunners are paying an initial £20m up front with a further £7m coming in add-ons. Arsenal and Mikel Arteta believe they submitted the registration paperwork in time for Trossard to be eligible to face Manchester United on Super Sunday, live on Sky Sports.
The 28-year-old has signed a four-and-a-half-year deal with the option for a further year.
"We are really happy to have him," said manager Arteta. "He's a player we have followed for a while now. The opportunity came and we have the necessity to have a player in the front line that is versatile enough to play in different positions. He knows the league, he has experience here and he can have an immediate impact in the team."
Finally, Arsenal secured the signing of Poland defender Jakub Kiwior from Spezia in a deal worth £20m.
The 22-year-old, who has signed a four-and-a-half deal with the option of a further year at the Emirates Stadium, becomes the Premier League leaders' second signing this January after the arrival of Leandro Trossard from Brighton for £27m.
On completing his move to north London, Kiwior said: "When I saw my name on an Arsenal shirt for the first time, I just laughed! I was so happy to see my name on the shirt of such a huge club. For me, it's an incredibly happy moment and the pinnacle to play for such a big club.
