Many of these weren't failures:

Lallana was captain, didn't fail.

There's a reason Lovren had to force the club to sell him.

Andy wasn't a failure, he was a young solid left back or else we wouldn't have bought him.

Salah's days at Chelsea were horrid, but at Fiorentina and Rome he upped his game, was on the Serie A team of the year by the time we got him and the only thing he missed was consistent finishing.

Gini Wijnaldum was one of Newcastle's best players, had a great World Cup in 2014 and was had a very good tenure in Holland.

Coutinho: I agree he was underwhelming at Inter but let's not forget that he was right next to Neymar on the list of Brazilian youth prospects.

Liverpool is not some magic factory for failed players mate
