Barcelona, who included six members of Spainâ€™s World Cup- winning side of 2010, have now won the European Cup four times and look unstoppable.
Ferdinand said: â€œNow they have set the standard and you have to get to that standard.
â€œThey are a fantastic football team with great individuals, but they are a great collective team â€“ they all know their jobs and play it well. You have to aim to get to that.
â€œRegardless of two years ago, we havenâ€™t done as well as we should have done.
â€œWe had a good game plan and maybe we didnâ€™t implement it as well as we could have.
â€œIt is just disappointing, really. We genuinely had the belief we were good enough to get a result but it did not materialise."
