Think I slightly disagree pal.
It in my opinion would mean the team all of a sudden is more mobile with no Barry. Meaning as long as Jagielka has a quick replacement as well that we could then push up as a team an extra 10/20 yards. Win the ball back higher up the pitch, break quicker etc. What it would mean though, is perhaps playing a creative type on one wing (?????), and then Bolasie on the other to compensate for the lack of guile from a Besic and Gueye pairing. A proper goalscoring #10 like Sigurdsson and then Lukaku. We can dream hey?
