JOE Gallen insisted Millwall's season had been "very successful" despite the fact they were spared relegation by virtue of other results on the final day.
The Lions needed a point against Derby County to be mathematically certain of survival, but Conor Sammon's goal five minutes from time condemned them to defeat at Pride Park
But Peterborough and Barnsley failed to get the wins that would have sent Millwall down to League One, leaving Gallen to reflect on a mixed campaign full of highs and lows.
He said: "We were disappointed to lose but to survive in such a strong division, whilst getting to an FA Cup semi-final, makes this a very successful season, although we might not feel that way.
"I knew what was going on in the other games but Kenny didn't. I didn't tell him the scores because things weren't looking good for us at one stage and we had to concentrate on our own job.
"Thankfully for us, to get over the line, some other teams have helped us out. It has been big game after big game for us recently, with no time to rest. Players were playing through injuries.
"Everybody needs to have a rest. There are only so many games you can motivate yourself for. It's been hard keeping everyone's spirits up when results have been going against us.
"But I think when you look back it's been a good season – it's been very up and down."
