His first season was always likely to be one spent acclimatising to life in a new country and at a new club and his vastly improved English is testament to his progress.
Rewind 12 months and he barely knew a word. The name 'Everton' and the words 'five-year contract' had put a smile on his face but he was very much at the start of a path.
"It was difficult at first," Gueye told evertonfc.com. "When I first came here I was a little homesick. I did not know many people, did not understand the language and did not know my way around.
"My English has really improved," he added. "Sylvain and Louis have helped me a lot and practise with me, also Seamus and Bily as we live in the same building. My girlfriend speaks very good English too and she helps me a lot.
"It has helped me settle. I like Liverpool and feel good here. The people are nice and I feel happy and confident living in the city. I have favourite restaurants, cafes and shops and feel good."
