I quite liked it, giving Farrah 10 minute break after half time, effectively gives him 20 minutes to get air back in the lungs and rest up to stay sharp for the final 30\. Think we might get more out of Robbie doing this, he lifted in the last 10.
Although I think that Cherrington is clearly a better option for that 10 mins than Halatau, the fact Haltau fills other roles and is versatile prob makes his overall value to the bench greater than CHerrington.
