2) Prone to expensive failures in the transfer market
Although Guardiola has rightly earned praise for bringing through some superb youngsters into his Barcelona team, he has also made some big blunders in the transfer market. Zlatan Ibrahimovic was an extremely expensive mistake during his reign at the Nou Camp, while Cesc Fabregas was another ill-thought out purchase as he struggled to find places for these players in his system. At Arsenal he simply won’t be able to afford to throw money away like that and may get found out.
