Shkodran Mustafi is confident fellow new Arsenal signing Lucas Perez has all the attributes to be a hit in England and warned Premier League defenders they face an "uncomfortable" experience.
Arsenal completed big-money deals to land centre-back Mustafi and forward Perez from Valencia and Deportivo La Coruna respectively before the transfer window closed.
Mustafi has first-hand experience of playing against his new team-mate in LaLiga and believes the 27-year-old can bring the sort of form that saw him net 17 league goals last season to Emirates Stadium.
"He is uncomfortable to play against. He's a good striker - he has everything a striker needs," he told Arsenal's official website.
"He's someone you can play well with. He doesn't just run around and wait for someone to give him a pass to score a goal. He works a lot for the team as well and he creates chances.
"He's in the right place at the right time, as he showed last year in LaLiga. I played there for two years and I know it's not that easy to score many goals in LaLiga, because you have great defenders there as well.
"I think he's going to help the team a lot."
