The most surprising transfer during this summer’s transfer window is surely David Luiz’s return to Chelsea for a fee of around £34 million.
The 29-year-old left Stamford Bridge to join Paris Saint-Germain in a £50m deal just two years ago but the Brazilian is on his way back to west London in a sensational move.
Understandably, some Chelsea fans aren’t entirely convinced with the transfer. Not only are they worried about the hefty transfer fee they’re paying for him, but they remember what he did back in the 2014/15 season.
Luiz scored an 86th-minute header in the Champions League last-16 at Stamford Bridge to send the tie into extra-time - which PSG went on to win.
But instead of respecting his former club and choosing not to celebrate, Luiz went mental and later had to apologise for his reaction.
Check out his celebration below:
While some supporters may not be impressed, you’d forgive Diego Costa for also having some reservations.
With the French club knocking out Chelsea in the Champions League in the previous two seasons, Luiz and Costa have clashed on numerous occasions. In fact, there is a three-minute YouTube clip of all of their shenanigans during matches.
While there are plenty of handbags throughout the video, one thing seems obvious; Luiz and Costa don’t particularly like each other.
The clip ends with the controversial striker planting a little headbutt on Luiz who falls over dramatically.
Check out the video below:
Despite all of their fighting on the pitch, Luiz has spoken of his relationship with Costa, describing him as a ‘big friend.’
"He's a big friend," Luiz said of Costa.
"Diego is a great player and his style of play is to play with contact, to speak, to intimidate. He tries to get defenders yellow cards.
"For all the match, he is bang, bang, bang.
"He can hit you on the head during the match and then after the match come and embrace you."
Maybe now they are teammates, they won’t stop the fighting and remain ‘big friends’ at Chelsea.
