Szczęsny signed a new 2-year contract. I think it's the right decision and he will be useful for Barca. He performed very well last season. What I don't understand is that Szczęsny announced last season that he was retiring from football and then he came back and signed a contract with Barca. Now he'll continue for two more seasons. Was he suffering from a burnout syndrome? After he decided to retire, I think he realized that he couldn't do without football and decided to play as long as he was physically capable. It'll be interesting to watch him fight for the jersey with Joan García.
It is quite surprise that Szczęsny signed new two years deal with Barcelona after saying he would retire but he likely felt tired from playing at top level and later realized how much he missed football. His strong performance last season probably convinced Barcelona to keep him especially with Marc André ter Stegen injured. Now it will be interesting to see him compete with young talent Joan García for starting goalkeeper spot which could be good for both players and team.
