مالانگ سار که پارسال از لیگ فرانسه به عنوان بازیکن آزاد به چلسی پیوسته بود ، به صورت قرضی به پورتو پیوست و در ۲۴ بازی به میدان رفت و عملکرد خوبی داشت حالا با برگشتن به باشگاه مالکش چلسی سعی میکند توجه توخل رو به خود جلب کند حالا که مارک گهی با ۲۰ میلیون یورو در آستانه پیوستن به پالاس قرار گرفته است این مدافع ۲۲ ساله فرانسوی به همراه جک کلارک سالتر سعی میکنند جایگاهی در ترکیب چلسی برای خود پیدا کنند بخشی از مصاحبه سار ؛
"I have spoken a little bit with the manager, he knows I speak French so we have been talking.
"I have a good feeling here; everybody is very good with me. I can feel everybody is ambitious here.
"They want to work and they really want us to give the best every day, and that’s a good thing because that’s how I see things.
"I really want to work hard every day and try to improve in every aspect.
"I hope to join the team and help the team to the top. They finished the season as Kings of Europe.
I’m here to help and to let the team stay at the highest level, trying to bring all the good energy and my work to the team.
"I know the club is ambitious and I am ambitious as well, so it’s a perfect match."
Sarr will have competition to break into the Chelsea first-team immediately, there's no doubt, but he could prove to be the up and coming star that many thought Guehi was going to be at Stamford Bridge
