Alonso told Spanish newspaper AS: "I know that things like this happen in football. I am calm, but it's a shame.
"I am disappointed because things were going so well. We were getting better, three wins in a row and after the match against Chelsea, the fixtures were good to climb up the league table.
"It was a hard tackle by Frank Lampard on my set foot. It is known that here the game is played very hard and this time it was my turn. He called me that night to apologise, we talked for a good while. He told me it was not ill intentioned. You thank the gesture."
