A perfectly legitimate argument.
And the legitimate argument gets badly harmed by the refusal to just deal with reality here.
Romero, Van De Ven, Solanke, Johnson, Udogie and Porro started all of the final 5 EL games, the QF, SF and Final. The whole back line and the two primary goalscorers, that was his core group that was fit during that period.
In the seven league games between Southampton on 6 April (which we won despite fielding a weakened team in preparation for the first leg with Frankfurt) and the final day against Brighton (which was after the final):
Van de Ven played 45 minutes total
Romero played two 90's, one other half, and was unused 4 times
Porro was an unused substitute 4 times
Udogie was an unused substitute 6 times
Solanke was an unused substitute twice, and came off the bench twice more
Johnson was an unused substitute twice, and came off the bench twice more
You just look stupid pretending this didn't happen, there's no other way to say it.
How is resting players tanking something? He had a squad. Many of the teams we played were still decent. We certainly weren’t throwing out youth teams to get destroyed.
We lost games where we didn’t rotate. We lost games where we did rotate. We lost games when we had no EL matches. Constantly. The shit run of form came long before the Europa league knockouts and concluded after we’d won the fucking thing.
Everyone rests players for Europe, it doesn’t mean they sacked it off and weren’t trying in the league. It’s a shit excuse. It’s a pathetic excuse. It’s the last refuge of the Angelina’s.
