For me and no bigger fan of Klich on this site than me, (some may remember I was the only Klich fan at one stage) but he was tired and injured last season and only had about 10 good games. Dallas covered for him well enough but having a 21yo combative midfielder putting you under pressure can only be good. Good for the future too as Klich is now a 30yo, Dallas is also over 30. Fact is some players let us down last season through injury, suspension or bad form at times. We lost points due to this and I think Bielsa is looking at all options that counter these issues.
