Mikel Arteta should try and make a major signing this summer to help improve the Arsenal team more than they are at the moment so that Arsenal can become one of the best teams in Europe
Actually, Arsenal doesn't need big players, with players like last season Arsenal can compete well, maybe the intention is good for a stronger squad, but does Arsenal have enough money to recruit big players just for the ambition of winning the Premier League title next season? I think that with the current players it is much safer than adding ammunition, unless there is a weak position in Arsenal's line, there is a big possibility that it could happen to bring in a player who can contribute well to Arsenal.
