He is usually the one covering a break as he isn't the tallest but has pace and can tackle.
Stoke should be a touch embarrassed that he was the one who won the header but delighted for him!
I was just about to post similar LL. He's always been the one on the half way line and though I can't be sure as I only seen it once but I am about 75% positive that Lennon was the one who was back on the half way line defending
If that's the case, that's the first time that Coleman has had a chance to get in the box at a corner from what I can ever remember. It may be a subtle change but it's an excellent one as Lennon with his pace can cover both sides on a counter, whilst Coleman is naturally more aggressive when attacking the ball in the air.
