Before the Sri Lanka-India game, former Lanka captain Kumar Sangakkara had a session with Kusal Mendis and the youngsters that worked wonders for them and even current skipper Angelo Mathews acknowledged his contribution.
Today, it was Smith, looking dapper in a black suit, who walked in at the Lord's indoor nets.
He watched the practice for around 35 minutes and was seen speaking to head coach Russell Domingo and other support staff, enquiring about their preparations.
"It's always nice to have Graeme around and have this kind of support away from home."
Smith is in England as a commentator for the Champions Trophy.
