Considering the state we where in when he first got the job he's right.....
We were perennial relegation candidates, constantly skint and wasting money on well past it big names.. ginola, gazza etc...
He came in, made us defensively sound and hard to beat.
We became the best of the rest, only behind the teams with mega money.
Many of his targets that we missed out on ended up being top players at top clubs, Essien,hazard, cech, moutinho, negredo, manolas etc
Challenging top 4/ finishing in Europe became the expectation rather than a pipe dream....
He may have failed to take the next step but he's been consistently the best manager we've had at the club since we last won the league....
