Is it me or is Chelsea's set up to defend this throw in really terrible? Cucurella is guaranteed to have a 2-v-1 overload here if Mbuemo manages to get there for the lay-off from the throw-in. Why was there not an extra man to cover the thrower? Cucurella should be tracking Mbuemo's run, or someone else should.
