Albion new boy Tariq Lamptey repaid the trust of Frank Lampard and his colleagues on a big derby day for Chelsea.

And that arguably speaks volumes for the talent and character of the 19-year-old the Seagulls secured on a three-and-a-half-year deal last night.

The 5ft 4in dynamo comes with a reputation for being able to play right-back or on the right of midfield.

It was in the former role he played his only Premier League match so far.

Lamptey’s lone Prem appearance lasted about 35 minutes.

But it was one which says an awful lot about why Albion have been keen to get him on board ahead of the deadline.

He went on as sub during the second half of a game at Arsenal a month ago, then played a part in the Blues coming from a goal down to win 2-1.

That had Lampard purring afterwards as he looked back on that match and ahead to the New Year’s Day trip to the Amex in his press conference at the Emirates.

He recalled how he turned to assistant Jody Morris as he decided whether to throw Lamptey into a highly competitive all-London tussle.

Lamptey replaced former Seagulls loanee Fikayo Tomori with his side 1-0 down to an Arsenal team fired up in Mikel Arteta’s first game in charge.

He immediately got to grips with the challenge in front of him and a terrific run and pass set up a chance for Tammy Abraham.

That one did not go in but Chelsea scored twice late on to take the points.

Lampard said: “Tariq Lamptey is a credit to Jody Morris and (coach) Joe Edwards.

“When we sat in the last few days and we knew (Cesar) Azpilicueta had a small injury and Reece James was injured, we were looking at options for a right-back, right-wingback.

“They said ‘Believe in him, trust in him’ because they did.

“I listened to that. We felt it was the right time to bring him into the game and he was a real catalyst.

“We were getting down the sides and he gave us a little bit more of an edge to that.”

Lampard revealed he had marked Lamptey down as one to watch for some time.

He added: “When I was doing my coaching badges, I did a lot of hours with the academy and the youth team.

“I saw him train a lot and I know he has a different dimension as a right-sided full-back or wingback.

“He has pace, a low centre of gravity, he can go by people and of course he wants to work on his end product and all the last bits.

“My question to Jody when he came on was ‘Has he got the confidence and the personality to deal with this?’.

“Jody said, ‘Yeah, no problem.’ When he turned inside and slipped Tammy in, I thought it was a great example of someone coming on a bit fearless.

“Sometimes you get that with youth.”

At the time the hope was Lamptey would agree a new deal at Stamford Bridge.

Lampard said: “Hopefully he feels a bit of love, the fact we parachuted him in.”

But Lamptey did not play in the next fixture.

Unfortunately for Dan Burn, Lampard went with the more robust James in the game at the Amex four days later.

That was the contest which ended with Burn nursing a broken collarbone.

Lamptey played in two FA Cup ties but Chelsea were unable to tie him down on a longer-term deal with both James and Azpilicueta ahead of him in the pecking order.

As for Lampard, he looked an unhappy figure as he spoke to media on the final day of the window.

It might not be the main cause of his frustration but he will know he lost a good one to the Seagulls on deadline day.
