Gabriel is being one of Lille's key players this season; which is why he raised interest in the transfer market. According to 'Le10Sports', both Arsenal and Everton tried to sign him, but they failed.
The amount of money involved hasn't came out, but taking into account the size of both clubs, it could have been quite high. The player's market value is almost 14 million euros, but his exit price could shoot up.
As a final blow to the Premier League sides, Lille officially announced his contract extension until 2023, thus completely protecting him from leaving. The rumours are expected to be over.
You have to take into account that this deal could also serve as an outright refusal for Arsenal and Everton in the summer market. If they were planning to try and go for him again, it looks like they'll have it much more complicated.
