Though in the league he has been poor this year.
No, he hasn't. He was playing well, especially linking up with Blackman, earlier in the season. Then he got injured, our form dipped , and he's been getting better each week since his return.
It's fair to say he should have contributed more goals in the league (likewise Vydra) but actually in terms of consistency he's been one of our better players when he's played this season.
