Jamie Roberts says his partnership with Brian O'Driscoll can improve
Wales centre Jamie Roberts is confident the Lions can square the series with South Africa in the second Test at Loftus Versfeld.
The Lions were 19-7 down at the break in Durban and lost 26-21 with Roberts among the tourists' best players.
He said: "Next week we've got it all to play for up at Loftus - we had a chance at the end there. The second-half was an outstanding performance."
He added: "We could have won that game and we'll take heart from that."
Roberts says the Lions overcame early disciplinary problems to claw their way back into the game.
He added: "We were fighting an uphill battle come half-time, but the way we came out in the second-half, the determination shown especially in the last half-hour/20 minutes was fantastic.
"If we're going to win next weekend that's the kind of intensity we need to play at.
"We had chances to score and we didn't and maybe on another day we'd have got them, but it's horrible to think this all comes down to 80 minutes and we just didn't click really in that first half.
"And that's something to address for next week. It's most definitely do-able."
Despite the plaudits earned by his midfield partnership with Brian O'Driscoll, Roberts believes he and the Irishman can improve.
"It's gone well so far, but we both made quite a few errors today [in the first Test]," said the Cardiff Blues' centre.
"We're far from the finished article and we've got a lot to work on in the week.
"Our attacking options can vary a bit and we got turned over a couple of times as well. We're always improving and hopefully we can carry the combination into next week."
