Brighton midfielder Pascal Gross has sung the praises of former teammate Leandro Trossard.
Trossard left Brighton for today's opponents Arsenal in January.
"He's doing really well, his football ability is incredible," Gross said. "He's quick, he can finish with his left and right foot, he can create.
"So he's a really good player. But we're looking forward to the game because it's another big opportunity for us.
"It will be nice to see him but we have to focus on ourselves."
