Olympique Marseille coach Jorge Sampaoli admits Sead Kolasinac may take time to settle in.

Kolasinac has signed an 18 month deal with OM after leaving Arsenal in January.

Sampaoli said: "The arrival of Kolasinac is made to have more options, so that Luan Peres can breathe. He and (Cedric) Bakambu will have to play even if they are not 100% ready. When you play every three days, you need to have different options.

"If they had been registered, they would have played against Lyon. In addition, for Kola, we must add the language barrier. He has to get used to the system and his teammates."
