Just look at the Torres transfer. He was in worse form, at the same age and he
clearly wanted to go yet he left for £50m. Ronaldo obviously wanted to leave us yet he went for a world record fee. This whole "you've got an unhappy player who will not be useful to you" suggestion comes up all the time but it's just pie in the sky stuff. Ronaldo was obviously a little distracted in 08/09 and wasn't on top of his game but he still had a big hand in us winning the title and we'd have had very little chance of reaching the CL final without him. And even though he was "unhappy" he still went for a huge sum. Likewise Berbatov was so adamant he wanted to leave that he refused to play/train (?) at the beginning of the league season yet we still paid over £30m. So much for no bargaining power.
The idea that he's no longer the player he once was based on one below-par season is bizarre. In the previous season he scored 27 league goals - a record Henry bettered just once and a record only 6 players have surpassed in Premier League history. In the season before that he was
the key player in our run to the Champions League final and a crucial part of our record-breaking title win. In terms of the league he's gotten 76 goals and 28 assists in the last 4 seasons or averaged a goal/assist every 94 minutes. In the last two seasons he's averaged a (league) goal/assist every 95 minutes. Last season he averaged a (league) goal/assist every 92 minutes. Yeah, he's on a pretty drastic decline.
The only reason people are jumping on the "Rooney's past it" bandwagon is because they've forgotten about his injuries and so the lack of goals is taken out of context. He played just 2017 league minutes last season which equates to just over 22 full games. It's the lowest amount in his United career. There's a clear correlation being fitness/playing time issues and goal returns in Rooney's last 5 seasons; in the two seasons he's played over 2500 minutes/started over 30 league games he's scored over 25 league goals, in the other three seasons he's scored under 15. It's not like he suddenly became poor in these seasons though, last season and in 10/11 because he couldn't be relied on to be our main goalscorer he simply took on a more creative role and allowed Berbatov/Hernández and van Persie to be our go-to man for goals. In both of those seasons he was one of just a handful of players to get into double figures for both goals and assists. Unless you've got some kind of evidence that he's now in such poor conditioning that he'll have to resign himself to starting under 30 league games every season from now on then any suggestion he's past his peak is clearly ridiculously knee-jerk.
