I loved Vidic, but he's gone, and I'm looking forward to what the future holds. He was a huge physical presence back there, and nobody in the Premier League, or even the world, comes close to the presence he had. Still, his lack of mobility was becoming more and more apparent in his final 2 seasons. LvG seems to want the centre backs to play quite high up the pitch. Not suicidal Villas-Boas high, but fairly high, and Vidic could struggle there.
Regardless, I think it was time to hand the future to the younger players anyway. We spent a combined £28million on Jones and Smalling, and they've not been given a fair crack of the whip yet. This is Smalling's 5th season with us! And Jones' 4th! And we're still talking about how they've not been given runs in their actual positions. Rio and Vida got the not whenever fit. They should have been established players by now really. Another year of Vidic would be another year of pushing back their development.
A lot of people, United fans and non-United fans, reckon we need to invest more in the defence, but I'm a little glad we didn't. Before we do spend on a top class centre back, I think Jones and Smalling need to show what they can do, and stake a claim on their United futures. There's a fair chance we already have two top class centre backs on our hands. Their injuries are concerning, but both have looked very good when played at centre back. I think both will go on to be top players and England starters, but they just need to stay fit for more than 3 games!
