Atletico Madrid manager Diego Simeone firmly believes Ghana international Thomas Partey can be a great success at his new club Arsenal.
"In these situations of the clauses, we cannot give many opinions. They are decisions that are made based on the possibility that exists," Simeone said.
"As for Thomas, everything that happens to the guys who have given me a lot makes me happy.
"I remember the games we saw him with the B team and when he started to come through.
"He went to Almeria; it was difficult for him to find a stable place but he is an extraordinary player. He will do well and we wish him the best. We love him very much."
