Christian has described his time at Everton as “amazing” after arriving on loan from Chelsea.
The Ghanaian international played 90 minutes against Swansea City as the Toffees were beaten 3-0 in the League Cup, and is hoping for more game time in Europe.
“It’s been amazing since I came to Everton,” he told the club’s official website. “Everyone is friendly and I’m settled with everyone now so I can just concentrate on games.
“It is very important that I already have experience [of playing in Europe] because it gives me confidence and I also think it boosts the confidence of the team.
“The Europa League is very important for everyone at Everton and it’s a big opportunity for me to prove myself as a player.”
