Two months after completing his move from the Potters to join the Reds, Carragher praised Shaqiri's impact on Liverpool's League performances so far this season despite his few minutes.
Speaking in an interview with BetVictor, Owen said: "This is a real test of Liverpool's title credentials and a win at Wembley will go a long way to proving their doubters wrong".

"That for me is more important".

Erdogan again described interest rates as a " tool of exploitation " but vowed that "we can not be taken advantage of". The central bank's move makes Turkey's interest rate one of the highest in the world.
"I think it's a brilliant buy for Liverpool", Carragher told Sky Sports.
Of course, you accept it because that's modern football, you just need to try and focus on the game but these games can often be slow starting and low on quality, because the players aren't fully rested and concentrated. It will be a very tough opponent.

The Watford crowd will be well up for it after the run they have been on, but United will have a plan and if they can be calm and control the game, it should be enough for three points.
"As a United fan, that's a worry because it is still that mentality of "anyone but them".
