Brighton midfielder Adam Lallana is reported to have been the player that had a huge bust-up with now former team-mate Leandro Trossard before his exit to Arsenal.
The Belgium international spent three-and-half-years on the south coast before upping sticks to the capital to ply his trade for the Gunners. While that is obviously a big step in Trossard's career, he may harbour some regrets over the way his time at Brighton came to an end.
It became common knowledge that the 28-year-old winger had fallen out with new Seagulls boss Roberto De Zerbi, who told reporters that Trossard would not feature against Liverpool last weekend due to showing a poor attitude in training, but what was unknown was the extent of his fall-out with Lallana.
