When players like Jayasuriya, Muralitharan, Sangakkara, Jayawardene and Malinga were in the Sri Lankan squad, I miss this squad a lot. Personally I am not a fan of Sri Lanka cricket. But I like Sangakkara, Jayasuriya and Malinga very much. I like Sangakkara's batting style. He was an excellent batsman and human being. But the current team in Sri Lanka is completely opposite. I think most of the players in the team are rude. They did not even shake hands with the Bangladeshi players after the game against Bangladesh. Also we see at times they behave strangely after getting a wicket. However, this is not a fault, but it seems strange to me. Players should be a little more patient. As they are professional players.
I think there is still same quality but there is something off. We saw good innings from Samarawickrama, Mendis, Perrera, Asalanka — although I'd agree they weren't consistent while Madhusanka as bowler was consistent throughout the tournament.
They say with confidence half game is won, there was none in Kusal when he talked during the toss. I think this affects the team as well, they don't have any veteran players that probably affects too.
Regarding not shaking hands with Bangladesh, they did this due Shakib - Angelo incident.
