On the face of it, he seemed to be the signing of the summer; Fabricio Coloccini was brought in at the staggering cost of £10m and was expected to finally solve the problem of a leaky Tyneside defence. Unfortunately, he has gone the way of Titus Bramble and Jean Alain Boumsong, and despite looking like a solid buy, has consistently been overpowered and too easily fooled.
For the away trip to Manchester City, Colo was moved into defensive midfield, his "favoured" position. It was hard to see why as he failed to complete a pass over five yards for the entire first half and was dropped back into the defence at half time.
The answer is a tough call that I wouldn't like to make, but it is a rather clear one. The Argentine defender must take a place on the bench whilst Steven Taylor and Sebastien Bassong are given the chance to expand on what promises to be a flourishing partnership.
Bassong has been something of a rarity for Newcastle in recent times, a good buy. Just one million pounds was spent to secure the Frenchman's signature and he has looked more than comfortable with the pace of the Premier League.
At the end of the day, it doesn't matter how much money you spend on a door, if it doesn't fit the hole, you can't use it.
