DIego Costa has not scored since the victory over Wigan

Chelsea striker Diego Costa has told IBTimes UK he deserves full credit for the second goal of the 2-0 win against Tottenham Hotspur in the League Cup final even though referee Anthony Taylor said Kyle Walker scored an own goal.

Captain John Terry gave Jose Mourinho's side the lead in the first-half before the Spaniard's shot was turned into Hugo Lloris's net by the leg of Walker after the break.

The Spain international, who has scored 17 goals this season but has struggled to add more to his tally since the 5-0 win over Swansea on 17 January, believes he deserves the credit of the goal, which saw Chelsea clinch their first trophy of the campaign.

Questioned by IBTimes UK after the game on who scored the second goal, Costa said: "It was mine, of course. I shot to the sticks. If I don't shoot there is no goal."

The striker once again played down his recent three-game ban for appearing to stamp on Liverpool's Emre Can during the League Cup semi-final, as well the intense battle he had during the final with the Spurs defenders.

"I don't care about what people say. I have the trust of my teammates and the manager. I know how I am, I know my way of being. What people say doesn't bother me. I know how I have to play on the ground," Costa said.

"I am calm about it. I am used to it. The defenders try to do their best in the same way I try to do my best. I provoked them and they provoke me. Both. This is normal on the ground. We all want to win. Nobody plays to lose. They tried to do their game and I do mine. I am going to keep fighting and working hard on the ground as always."

Chelsea advantage as Liverpool beat City

Meanwhile, the striker was cautious when questioned whether Manchester City's defeat to Liverpool left Chelsea in a strong position to win the Premier League.

"The main thing was to win our game against Tottenham. It was our first final and winning it was our only thought. Now we can enjoy the victory but from tomorrow we have to think and be focused in the next game on Wednesday [against West Ham]. If we win, then the Manchester City defeat will worth it but if we lose, it will be useless," Costa said.

"We go little by little. Thinking about the treble now is nonsense. We are aware that we have a squad to fight for a lot of titles and we will do it but game by game."

Costa won La Liga and reached the Champions League final with Atletico Madrid last season. Asked whether he believes Chelsea are as strong as his former side, he said: "We are different teams.

"At Atletico last season we were very well worked. We had the feeling that we could reach the Champions League final and win it. We had a great season. But Chelsea are different. Here, we also try to do as well as we can. We also have a great team and a great manager and we know that we can conquer big things."
