The 33-year-old withdrew injured following a head clash with team-mate John Flanagan as the Reds cancelled out Arsenal's injury-time penalty with one of their own in a 1-1 draw on Sunday.

Next season would get more competitive, with City, United, Chelsea and Liv making more quality signings.. Arsenal should seriously think about winning something.
