Joe Allen scored two goals for Stoke on Saturday – and Liverpool fans were shocked on Twitter with his performance.

Stoke recorded a crucial 2-0 victory against Sunderland and picked up their first league win of the season.

Allen, 26, opened the scoring after just eight minutes with a close-range header from a Marko Arnautovic cross.

He then doubled Stoke’s advantage on the stroke of half-time with a left footed shot into the bottom right corner.

Allen has now scored four goals in his last three Premier League games and has become an instant favourite at his new club.

The Welsh international moved to Stoke in the summer and ended his four-year stay at Anfield.

The central midfielder was a consistent performer at Liverpool, but was deemed surplus to requirements by Jurgen Klopp.

Liverpool fans were surprised on Twitter with Allen’s display and several fans admitted they wish he had stayed at the club.

Here is a selection of their messages on Twitter:

Allen has been in phenomenal form this season in a struggling side and continued his impressive start during the international break.

The midfielder netted a fantastic long-range effort for Wales against Austria in a World Cup qualifier, which eventually finished as a 2-2 draw.

Liverpool may now be regretting selling Allen, but there were no signs of his goal scoring capabilities while he was at Anfield.

Allen scored just seven goals in 132 appearances for the Merseyside club and he is set to surpass that record in no time at Stoke.

The Reds have been in impressive attacking form themselves and have scored 18 goals in just seven league games this campaign.
