Arsenal defender Nacho Monreal says the club made the right decision in spending big money to sign Shkodran Mustafi and Lucas Perez on the last week of the summer transfer window.
The Spaniard says the Germany international will "find it easy" to settle down in London as he praised the 27-year-old striker who will contribute because of his versatility.
"He [Shkodran Mustafi] will find it easy to adapt to the club," Monreal told Arsenal Player.
"He has already lived abroad, he speaks the language and he knows Mesut Ozil.
"All those elements will lessen the impact of changing environments. Luckily for him, he will feel at home from the very first day.
"Mustafi is a player I like. He is experienced and really tough to beat, which makes him very suitable for the Premier League's style.
"We really needed to bring a centre back to the club considering Per Mertesacker and Gabriel's injuries, as well as Calum Chambers' departure on loan.
"I hope he feels happy here from the very beginning so he can do for us what he does best.
"Lucas Perez is a great striker.
"I know him very well because I follow La Liga quite a lot. I enjoyed watching him play last season. He had a fantastic campaign, scoring 17 league goals, despite not playing for one of the strongest teams.
"He can contribute with many things for Arsenal because he is different to the rest of the players in the squad. He is quick, left-footed and he finds spaces really easily. He is going to help us a lot.
"After having a few training sessions with him, I can say that I am very surprised with him. He is a very good player and he will fit into the group nicely."
