No of course not but I think he would have sorted the problem.
Jags, Howard, Barry and Baines were finished. With spending the money on Lukaku he couldn't replace them all at once.
But Rom and Stones would have been sold and I think he would have done a better job rebuilding with that money.
He couldn't have done much worse.
Look Martinez wasn't perfect but in hindsight perhaps we didn't give him enough time.
My real problem though was the choice of the people to replace him. How he ever thought Walsh and Koeman were up to the job I will never know.
