5 years is a long time for someone with such a patchy transfer record.
Successful signings (so far)
Daniel Sturridge Chelsea£12,000,000 (safe to say, that if we sold him now we'd make a profit)
Philippe Coutinho Inter Milan £8,600,000 (ditto)
Simon Mignolet Sunderland £10,000,000
Kolo Toure Man City Free (hasn't played many games, so he has the potential to go downhill rapidly. But most people have been pleasantly surprised by his performances)
Total 30,600,000
Unsuccessful signings (so far)
Fabio Borini Roma £10,400,000 (could turn it round, but I doubt it)
Joe Allen Swansea £15,000,000 (there will be a few that defend him, but so far we have spent 15 million on someone who hasn't played well enough to establish himself in the first team despite the team being weak in that area)
Oussama Assaidi Heerenveen £2,400,000
Nuri Sahin Real Madrid Loan (I'm sure he cost us a fee)
Iago Aspas Celta Vigo £7,500,000 (could turn it round, but I doubt it)
Aly Cissokho Valencia Loan (I think most of us agree on this one)
Total 35,300,000
Youth
Samed Yesil Bayer Leverkusen £1,000,00030
Luis Alberto Sevilla £6,800,000 (he'd need to be good for this price)
Tiago Ilori Sporting CP £7,000,000 (ditto)
Too early
Mamadou Sakho PSG £15,000,000 (Looked promising so far, but he is on the bench whilst the player he was bought to replace starts)
Victor Moses Chelsea Loan (Might be a bit generous putting him in the too early camp)
