Something interesting has happened over the last 10 years in the Premier League. Players who once would have been discarded as expensive and too old have become important parts of title-winning squads.
In my 20 years in football, I was fortunate enough never to have experienced relegation. And while there is the pressure of expectations at the top of the league, at the bottom it comes in fear and trepidation, which is almost worse.
A coach once told me there are four factors that determine a players' performance: his tactical awareness, his physical condition, his technical ability and his mental strength.
A collection of strong-minded individuals who have learned how to dismiss mistakes, disappointments and problems in their personal life make up a strong team. If the majority of the team have that then, as a unit, you are almost impossible to beat.
I developed a mechanism so that whatever mistakes I made, I would bounce straight back. Whatever was happening off the pitch, I could put it to one side and maintain my form. Call it mental resilience or a strong mind, but that is what we mean when we talk about experience in a football team.
The best managers out there at the moment are Pep Guardiola and Jose Mourinho but they are at other clubs - Real Madrid and Barcelona.
