Arsenal manager Unai Emery insists patience is needed with record-signing Nicolas Pepe.

The Ivorian continued his underwhelming start to life in North London by missing a sitter in the 1-0 loss to Sheffield United on Monday.

But Emery says Pepe needs time to adapt to Premier League football.

"We need patience," he said. "Pepe is improving. On Monday, the key to win was with him. If he scores the first goal, it's different.

"But it's one process and I believe in him and I know he needs time and patience."
