Reaching 4 semi-finals, Europa league final and finishing 3rd/2nd in his first full seasons. Bringing in exciting, quality players which have improved the first team whilst developing the likes of Shaw into one of the best in his position. But because he hasn't won a trophy yet, this is mediocrity to you?
He has deserved this extension because of the progress we have made since appointing him. I think some people on here need to seriously look back and see where we were heading as a football club before Ole took over. He has done a fantastic job!
Tuchel came into Chelsea on the back of them having a splurge on serious talent in the transfer market that Lampard could not get the best out of. Not taking away from any of his achievements, but Tuchel inherited a much better team and club in Chelsea than Ole did with Utd, that is just a fact.
