Reds defender Jonny Evans says the standard of football in the Premier League is higher than ever.

Despite United's upper hand in the title race, Evans insists City's players won't have given up hope of catching the Reds.
"Although there are only four games left their lead over us changed pretty quickly so it can happen the other way. We're
