Chelsea are 20 points behind leaders Manchester City in the Premier League this season, but Blues boss Thomas Tuchel is determined to bridge that gap next term.

"We have to accept there is a gap between us and Manchester City," he says.

"If you look at the fixture in the Premier League and the fixtures in the last years we have to accept this.

"And it's important that we accept this without making ourselves too small. From day one of next season we we will hunt them. We will try to close the gap between us."

It would have been a worthy final - and it may yet be a worthy final of the Champions League. Chelsea against Manchester City gets the hairs on the back of the neck standing up. It could be a wonderful game of football.

Against Palace last weekend and in Seville against Porto, Chelsea delivered two quite different, but equally impressive, performances.

At Palace, their attacking players clicked in a thrilling demolition of Roy Hodgson's side. The first half was probably their best 45 minutes under Thomas Tuchel. Against Porto, they displayed a defensive resolve which allowed their opponent almost no encouragement that a two-goal deficit could be overturned. To beat City, Chelsea will need to combine the best of both those displays.

Pep Guardiola's side have been incredible since mid-December when a home draw against West Brom left them ninth in the Premier League. The pace they have set ever since has been far too hot for anyone to live with and the quadruple dream remains alive.

But the tantalising delight of this semi-final is that City are not perfect - as both Leeds and Manchester United have demonstrated recently. They can occasionally be exposed; they do have off days and Chelsea do have the quality to exploit any weaknesses.

If the stars align, this might one of those classic matches we'll remember for years.

Is the impossible becoming a reality?

Pep Guardiola has long said achieving a historic quadruple is almost impossible but his Manchester City side took a giant step towards it happening by reaching the Champions League semi-finals in midweek.

Today they have the chance to move another step closer as they take on Chelsea in the semi-finals of the FA Cup.

The Blues will not make it easy, however, with Thomas Tuchel’s side having point to prove after finishing as runners-up in last year’s competition.

Two footballing heavyweights with all to play for. It sets things up for a classic FA Cup encounter.
